The results of detailed numerical simulations of the Richtmyer--Meshkov instability of the interface between layers of air and either helium or SF{sub 6} in a shock tube are reported. Two- and three-dimensional simulations based on both the Euler and Navier--Stokes equations were obtained by a finite difference method that employs a front-tracking technique to keep the interface sharp. The nature of the flow patterns induced by the instability is discussed. The results of a numerical resolution study and a demonstration of the influence of boundary layers are presented also. Agreement with experimental data is found to be satisfactory, with the exception of the initial instability growth rate.
