APPLICATION OF THE VISAR METHOD TO STUDY THE INTERACTION OF THE SHOCK FRONT IN THE GAS AND SOLID SURFACE

Abstract

. The paper considers the development of experimental methods for the study of physical and chemical processes in shock waves. The VISAR laser interferometry method is used to measure the velocity of a free surface of a solid body interacting with the front of a gas shock wave. For the first time, free surface velocity profiles are obtained in interaction with a shock wave in a light and a relatively heavy gas. It is shown that the method provides a higher temporal resolution than the laser schlieren method applied to shock waves, which makes it promising for measuring the structure of the shock wave front in gases.
