Droplets deposited on a sufficiently hot surface experience an interesting phenomenon. They skid on a layer of vapor that prevents contact with the solid surface. This is known as the Leidenfrost effect. It was first reported in the 18th century [1] and it is still the subject of intense experimental [2,3,4], theoretical [5], and computational … Read more
Brief history of droplet impact 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 … Read more
In this article, we’d like to discuss another interesting topic: computational fluid dynamics, also referred to as CFD and the different fields CFD is used in.
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 … Read more
Take a closer look at why high frame rate cameras are so useful in academic research.
