HYDRODYNAMIC PHENOMENA DURING HIGH SPEED COLLISION BETWEEN LIQUID DROPLET AND RIGID PLANE

The dynamics of high-speed impact between a compressible water droplet and a rigid solid surface is investigated analytically. The purpose of the study is to examine the mechanism leading to the erosion of a material due to liquid impingement. A Compressible-Cell-and-Marker (ComCAM) numerical method is developed to solve the differential equations governing the unsteady, two-dimensional liquid-solid impact phenomena. The method is designed to solve this steady portion up until the flow reasonably approaches the steady state solution. The validity of the method is confirmed by comparing its numerical results with the idealized exact solution for the classical one-dimensional liquid impact problem. The accuracy of the numerical results is found to be very good in that only slight numerical oscillations occur.
