Despite the attention the topic has received, there are still fundamental questions that are waiting to be resolved. For instance, for a stable and steady vapor film between the droplet and the solid surface how can this film be obtained? Also, what is the droplet dynamics like when the transition from boiling to the Leidenfrost effect takes place. Answers to these questions are not motivated by mere curiosity. They have direct implications relevant to industrial processes, i.e., cooling technologies [6].

The variations of the vapor film depend on the droplet size, i.e., if it is smaller or larger than the capillary length of the droplet, the length scale that associates surface tension and gravity. In small droplets, smaller than the capillary length, surface tension dominates, thus the droplet acquires an almost spherical shape. When the droplets are larger than the capillary length, the droplet tends to flatten. For even larger droplets, the vapor accumulates underneath the droplet and erupts from its upper part.

Droplets in the Leidenfrost regime can be recorded at a few thousands frames per second. The new Chronos 4K12 allows users to record footage at up to 1397 fps in 4K resolution or at 3651 fps in HD. Even higher frame rates are available at reduced resolution. These frame rates are sufficient to perform fundamental studies that have significant impact in a number of scientific and technological areas. If you have questions regarding the Chronos cameras, do not hesitate to send us a message. We are glad to be able to help you.

The study of droplet impact can be traced back to the nineteenth century, with the pioneering work by Worthington[1]. His book, published in the 1890’s, portrays outstanding images of individual droplets[2] after impact with a solid surface. The volume contains images drawn by hand. A variable time delay triggered a short-lived electric spark to illuminate the scene. Hence he could observe a specific shape of the droplet at different stages of the impact process. In later instances he used a photographic camera. This removed the subjectivity of his interpretation when drawing the droplet shape from his recollection. 

Worthington noticed a couple of facts. First: “the event takes place in the twinkling of the eye”. Second, he wrote, “it is an exquisite phenomenon that illustrates some of the fundamental properties of fluids”.

Certainly the event is fast, thus many of its features eluded clarification for decades. He was totally right in his second remark. The beauty of this seemingly innocuous process still captivates the eyes of the public nowadays all over the world when presented in slow motion or in still frames.

Little did he know that his work would motivate a large number of scholars to continue investigating this field. In fact, the interest in the subject is still strong nowadays, almost 150 since his seminal work. Interestingly, a significant number of phenomena have been more thoroughly understood only in the last couple of decades due to the advances in high-speed imaging and optical components. High-frame rates coupled with strong optics allow researchers to record finer details of the underlying mechanisms of droplet impact. This has resulted in a surge in publications related to this remarkable theme relevant to large number of fields. In industry, it is related to spray painting, fuel injection, cooling, inkjet printing, 3D printing, biological material deposition, agriculture and power generation, to name a few [3–6]. 

In nature, the impact of raindrops creates splashing which produces aerosols[4,6]. We all have experienced the smell of fresh soil on a rainy day[7]. Yet, this same mechanism has been associated with foliar disease outbreaks and pathogen dispersion[8].

Enhance your study of droplets with Chronos High-Speed Cameras

A typical droplet impact event is completed in a few milliseconds. Thus, it is especially suited for the frame rates of the Chronos High-Speed Cameras. For instance, if the impact velocity is only a few m/s a high-speed camera recording at 1 to 5 kHz provides enough information to resolve the impact of the droplet against the solid substrate. Also, with a pixel size of the Chronos 1.4 and 2.1-HD cameras, 6.6 and 10 μm respectively, the Chronos cameras provide sufficient spatial resolution  when coupled to a macro lens. Figure 1 displays an example of the impact of a coffee droplet with a solid surface. The images resolve the thin film produced as the droplet expands on the solid wall, left image, lower row. Also, the small receding waves moving towards the center of the film, are well resolved in the center image, lower row.   

Figure 1. Impact of a coffee droplet on a solid surface

Figure 2 displays the impact of a coffee droplet on a pool of coffee. The initial splashing of tiny droplets is seen in the first image on the left side. The “Worthington jet” that emerges after the cavity opened by the droplet closes is depicted in the central image. The image on the right depicts a satellite droplet about to be detached from the liquid column below. The thickness of the neck joining the satellite droplet and the liquid column is only 260 μm. You can take a look at our gallery of droplet impact to see the beauty created by these rather simple events.

CFD

What is Computational Fluid Dynamics?

In this article, we’d like to discuss  another interesting topic: computational fluid dynamics, also referred to as CFD. This is the branch of fluid mechanics that deals with the solution of the governing equations of fluid dynamics using computers [1].

As mentioned in our Fluid Dynamics Blog (link to the blog), fluid mechanics has a robust theoretical foundation. However, the equations that describe the motion of fluids, the Navier-Stokes (NS) equations, are difficult to treat analytically. There are a few exact solutions, albeit for highly idealized situations. Due to this, they only sometimes correspond to cases of practical relevance. Yet, they are useful as a benchmark to evaluate the performance of models that solve the NS equation numerically.

The advent of powerful computers enabled researchers to treat sets of differential equations as a set of algebraic equations that could provide solutions that otherwise would not be possible to obtain. With the development of faster and more compact computers, the field of CFD grew as well. Nowadays, corporations as well as research facilities make use of CFD as part of their R&D activities. Individuals willing to analyze relatively simple cases can do so in a personal computer. The subject is also taught in a large number of universities around the world, with the leading universities exposing their students to work in cutting-edge projects, thus significantly enhancing their academic background. 

CFD

What fields use Computational Fluid Dynamics? 

CFD has been applied to a large number of fields i.e., weather prediction[2], turbomachinery design[3], aerodynamics[4], combustion[5], aerospace[6], medicine[7], and food processing[8], to name a few. Recently, the complex features present in the flight of a hummingbird have been simulated by Ren et al. (2016)[9]. The authors point out that this type of work is crucial to get a deeper understanding of the complex wing-body interaction of different insects and birds and their flight mechanisms for maneuvering. Also, the results of this type of study can be useful to design and improve the performance of the next-generation micro aerial vehicles.

Recent videos captured by Christian Sasse using a Chronos high-speed camera also portray the complex maneuvers performed by these tiny creatures[10,11]. The wings of insects induce a flow in their vicinity that can be used to confuse their prey, as can be seen in the video shown here below. The flow created by the flapping of the insect’s wings cannot be seen yet its effect can be certainly felt. 

In summary, in the present blog, we want to highlight how the combination of high-speed video footage and data provided by CFD can significantly enhance our understanding of processes that otherwise would not be easy to clarify. Also, it can lead to bioinspired products of higher performance than those currently available to the public.

If you are interested in the topic you may take a look at a few popular textbooks on CFD listed in the References section[12, 13, 14, 15]. The literature on CFD is quite vast, thus here we present only a very small sample.

Fluid mechanics describes the flow of fluid whether at rest or in motion¹. The surface of the earth is covered approximately by 75% water and its atmosphere consists of air, a mixture of gasses. There is a wealth of nature and man-made applications related to this subject. If you think about it, it is difficult to pinpoint an application that does not involve a fluid flow phenomenon. The flight of an airplane, the liquid flow used to produce electric power, the flow in the arteries and the droplet ejection for printing are all fluid flow problems. 

This fascinating discipline has a sound theoretical foundation. Yet, the fundamental equations that describe fluid motion are difficult to solve by analytical means. Only a few exact solutions are available and they relate to highly simplified situations. Nevertheless, to validate theoretical models empirical evidence is required. In this aspect the field of fluid mechanics is rich in experimental methods, many of which have been available for decades now. If interested, take a look at the books by Merzkirch² and Smits³, they discuss different flow visualization techniques, listed in the references section at the end of this blog.

The Beginning of High-Speed Photography

One of the many techniques available is the use of images to analyze fluid motion. The technique goes back to the 19th century with the pioneer work by Muybridge to settle a discussion related to horse galloping⁴. Back then, it was speculated that a horse keeps at least one hoot on the ground when galloping. Surprisingly, his results portrayed a different story. First, the pictures showed that for a brief time the four legs of the horse are in the air. In addition to that, the footage depicted a rather complex motion of the horse’s limbs. It also showed no strongly synchronized motion of the two front members or of the rear ones. Muybridge’s work was not unnoticed. Soon, other people realized the value of the technique to analyze fast-occurring events. In the last few decades the use of high-speed footage has extended to a large number of fields in science and engineering.

Benefits of using High-Speed Cameras to analyze Fluid Motion

By using a high-frame rate of recording researchers can gain a deeper understanding of phenomena under study. High-speed cameras can record a larger number of frames per second than regular cameras. This provides the user with detailed visualization of fast-evolving fluid flow phenomena. Hence, these remarkable devices can reveal intricate flow patterns, turbulence, vortices, and other interesting flow features.

Moreover, the use of high-speed cameras combined with flow visualization techniques, i.e. PIV, has significantly improved our understanding of a large number of topics related to turbomachinery⁵, forensic analysis⁶ and multiphase flow research⁷, among others. Similar things can be said about the schlieren technique, changes of fluid density can be observed at time scales that are beyond the regular temporal resolution of commercially available cameras. In addition to that, both Particle Image Velocimetry (PIV) and schlieren are non-intrusive techniques which makes them attractive for different studies of fluid motion.

How High Speed Cameras are used by Academic Researchers and Universities

Impact of a Droplet onto a Cubic Pillar

Whether research studies are conducted at a large corporation, academic institution or military facility, fluid flow research can be demanding in terms of economic resources. Due to this, not all universities or colleges can offer students to get them involved in cutting edge research projects. However, some recent publications show it is possible to conduct high-caliber research work incorporating cost-effective equipment. In particular we want to mention a couple of studies that have been conducted making use of a cost-effective approach. Ren et al⁸ evaluated the impact of a droplet onto a cubic pillar experimentally and with numerical simulations. The team recorded the droplet impact using two Photron cameras as well as a Chronos 1.4 color camera. For the numerical results that used an in-house developed package, Free Surface 3D (FS3D), their numerical results agree well with their experimental results. Ren et al have managed to unravel how the point of impact between the droplet and micropillar strongly affects both the location and volume of entrapped gas.

Particle Image Velocimetry 

Luberto and Payrebrune⁹ recently proposed a low-cost particle image velocimetry. The spatial resolution of their system is comparable to professional systems. Moreover, they do not use a high power laser for the illumination of tracer particles, an attractive feature in terms of safety. For their experimental work, they used a Chronos 1.4 high-speed camera. Then they processed the PIV data using the MATLAB-based package PIV-lab. The authors supplemented their work with CFD (Computational Fluid Dynamics) simulations using the open source package openFOAM. Similar to the work by Ren, the relevant feature of their work is that they demonstrate it is possible to carry out competitive research work with cost-effective equipment. More importantly, they present their results in open access journals, thus making their results available to a wide audience.

These research studies resonate with our mentality here at Kron Technologies. We are also committed to provide cost-effective imaging solutions of top quality. This is not something taken lightly, our systems are employed in prestigious academic, industrial and research facilities all over the world.

For the last few decades high-speed cameras have been impacting different fields of science and engineering. Biology, chemistry, and physics are just a few areas where these remarkable devices are transforming the way we scrutinize and understand our world. The cameras’ ability to capture fast-occurring phenomena opens up new avenues for exploration and discovery.

In this blog post, we will inspect how these cutting-edge instruments are supporting academic research and what insights they are giving us into some of science and engineering’s most challenging questions. Let’s take a closer look at why high frame rate cameras are so useful in academic research.

Benefits 

In the past, studying fast-moving phenomena was often difficult or impossible due to the limitations of technology. Also, due to the expensive price of imaging equipment, its use was mostly confined to the laboratories of academic institutions, private companies or military facilities. Nowadays, high frame rate equipment is more affordable, hence we are experiencing a burst of exciting discoveries regularly. Here at Kron Technologies, we are committed to provide reliable and affordable cameras to individuals willing to unravel the beauty of the hidden world in plain sight. 

One camera, unlimited academic applications

Recently, the use of these truly remarkable devices has been applied to study fundamental problems of relevant industrial, environmental and scientific interest. For instance droplet motion on a patterned surface[1], secondary ice formation from supercooled water drop collision[2] and the evaluation of sensory information encoding using a biomimetic dynamic sonar emitting device[3]. The findings from these works can pave the way to design more efficient microfluidic devices, broaden our understanding of the formation of ice in clouds and shed new light into the acoustic emission pattern used by certain species of bats, respectively. Chronos cameras have been part of these efforts. Moreover, we expect to see a larger number of studies relying on our devices in the near future. There are other interesting applications related to biology[4], environmental science[5, 9] and engineering[6]. We kindly encourage you to take a look at them and see how Chronos cameras can provide solutions to your scientific, commercial or personal needs.

The burst of applications involving high-speed cameras is due to their temporal and spatial versatility. They can be used to evaluate the motion of submillimeter objects that experience rapid changes, i.e., the deformation and stretching of cells as well as the mechanics of high-performance athletes. We cannot overlook the significant difference in length scale of these two applications. Furthermore, Chronos cameras can be utilized to record the splashing of an ice cube dropped in a glass full of a soft drink to be advertised, an application that requires a few hundreds to approximately 1000 frames per second (fps). Or to record events that require a higher imaging rate to be properly visualized. See the images of high-pressure propellant spray exiting from a nozzle at 21,650 fps[7]. 

With this we want to highlight that fast framing rate devices can be deployed by seasoned professionals to complement their work as well as by individuals willing to try out new techniques that span beyond the traditionally available 30 fps. We also expect that with time more students, both undergraduate and graduate, embrace fast imaging techniques to support their scholarly activities. The recently completed work by Ikechukwu[8] on assessing efficiency of macro particle classification is testimony of this hope.  

In summary, the possible scenarios where high frame rate cameras can be employed offers a wealth of opportunities to venture into. By all means, if you have any comments or questions about your high-speed imaging needs, reach out to our team at Kron Technologies. We are happy to support your efforts and make your ideas a reality.

Gone are the days of relying solely on coaches’ eyes to improve athletic performance. Thanks to the advancements in technology, high-speed cameras have taken over the sports world, revolutionizing swing analysis and boosting athleticism like never before. In this blog post, we’ll dive into the science behind how these powerful tools are changing the game for athletes everywhere.

Introduction to Swing Analysis

There are a lot of different ways to analyze a golf swing, but high-speed cameras are becoming increasingly popular. Why? Because they can provide detailed information about the mechanics of the swing that can help golfers make necessary adjustments.

While there are many factors that go into a good golf swing, there are three main elements that a high-speed camera can help identify: clubhead speed, clubface angle, and attack angle. By analyzing these elements, golfers and their instructors can pinpoint areas of improvement.

Clubhead speed is perhaps the most important factor in determining distance. A high-speed camera can capture clubhead speed at impact, which can then be used to calculate how fast the club was moving at various points throughout the swing. This information can be used to help a golfer generate more speed or make necessary adjustments to their swing.

Clubface angle is another important element that can affect both accuracy and distance. A high-speed camera can help identify when the clubface is open or closed at impact, which can be used to make necessary corrections. Attack angle is also captured by high-speed cameras, and this information can be used to ensure that the club is entering the ball on the correct path.

By using high-speed cameras to capture all of this data, golfers and their instructors can get a much clearer picture of what’s happening during the swing. With this information, they can make more informed decisions about what needs to be changed.

How Highspeed Cameras are Used in Swing Analysis

Highspeed cameras are becoming increasingly popular in the world of swing analysis. This is because they offer a level of detail and accuracy that was previously impossible to achieve. By analyzing a player’s swing at high speeds, coaches and trainers can identify small flaws and correct them. This can lead to big improvements in performance.

There are many different ways that highspeed cameras can be used to analyze a swing. One common method is to use two cameras, set up at different angles, to capture the action. This allows for a side-by-side comparison of the two swings. Another method is to use a single camera to capture the action from start to finish. This provides a more detailed view of the entire swing.

Once the footage has been captured, it can be slow down and studied frame by frame. This allows coaches and trainers to see exactly what is happening at each stage of the swing. By identifying small flaws, they can make corrections that will lead to big improvements in performance.

The Benefits of Using Highspeed Cameras

Highspeed cameras are becoming increasingly popular in the world of sports. Their ability to capture very fast movements makes them ideal for analyzing an athlete’s technique. Here are some of the benefits of using highspeed cameras for swing analysis:

• Increased accuracy – Highspeed cameras allow you to slow down the action and see things that you would miss if you were just watching in real time. This can help you identify small improvements that can make a big difference in your performance.

• Better understanding of the mechanics – When you analyze your swing with a highspeed camera, you can get a better understanding of the mechanics involved. This can help you make adjustments to improve your technique.

• Greater insight into your strengths and weaknesses – By looking at your swing from different angles, you can get a better idea of what areas need improvement. This knowledge can help you focus your training so that you can make the most progress possible.

• Improved performance – The ability to see your swing in slow motion and identify areas for improvement can lead to better performance on the field or court. Highspeed cameras can help you take your game to the next level.

How Swing Analysis is Improving Sports Performance

Swing analysis is the process of using high-speed cameras to capture and analyze an athlete’s movement. This technology is often used in golf and baseball, but can be applied to any sport where improving performance through proper technique is a priority.

There are many benefits to swing analysis, but the most important is that it provides athletes with feedback that they can use to improve their technique. When an athlete knows exactly what they need to work on, they can make the necessary adjustments and see real results on the field or court.

Another benefit of swing analysis is that it can help coaches identify areas where their athletes need improvement. By analyzing an athlete’s swing, coaches can pinpoint specific areas that need attention and create customized training programs to help their athletes reach their full potential.

Finally, swing analysis is a valuable tool for research purposes. By studying how athletes move, scientists can learn more about human movement and performance. This knowledge can then be used to develop new training methods and techniques that will help athletes of all levels reach their goals.

Case Studies of Professional Athletes Utilizing Swing Analysis

Introduction to 3D Printing, Additive Manufacturing

The three-dimensional printing process is a slow and often tedious one. But, with the right tools in place, it can be the key to improving your 3D printing processes. 

First, let’s take a look at how the 3D printing process works. In general, there are three main steps to the process: modeling, slicing, and printing.

Modeling is the first step and involves creating a 3D model of the object you want to print. This can be done using CAD software or by scanning an existing object.

Slicing is the second step and involves breaking down the 3D model into thin layers that can be printed one at a time. This is usually done with special slicing software.

Printing is the third and final step. This is where the actual printing takes place, layer by layer, until the object is complete.
