A splash after half a brick hits the water; the image is about half a meter across. Note the freely moving airborne water droplets, a phenomenon typical of high Reynolds number flows; the intricate non-spherical shapes of the droplets show that the Weber number is high. Also note the entrained bubbles in the body of the water, and an expanding ...
[citation needed] Historically, Worthington (1908) was the first one who systematically investigated the splash dynamics using photographs. [citation needed] Splashes are characterized by transient ballistic flow, and are governed by the Reynolds number and the Weber number. In the image of a brick splashing into water, one can identify freely ...
As the Weber number increases, the drop deformation upon impact also increases. The drop deformation pattern can be split up into regimes based on the Weber number. [7] At We << 1, there is not significant deformation. For We on the order of 1, the drop experiences significant deformation, and flattens somewhat on the surface.
Relevant fluid dynamics non-dimensional parameters include the Bond number, the Weber number, and the Reynolds number. Water sloshing in a glass cup Slosh is an important effect for spacecraft, [ 4 ] ships, [ 3 ] some land vehicles and some aircraft .
Dimensionless numbers (or characteristic numbers) have an important role in analyzing the behavior of fluids and their flow as well as in other transport phenomena. [1] They include the Reynolds and the Mach numbers, which describe as ratios the relative magnitude of fluid and physical system characteristics, such as density, viscosity, speed of sound, and flow speed.
