Abstract:
A numerical simulation of the evolution and interaction of flow discontinuities in a channel caused by a pulsed volume discharge has been performed. The algorithm is based on a system of quasi-gasdynamic equations in compact form. A comparison is made with experimental data and calculation results based on the Euler and Navier–Stokes equations.
Keywords:
quasi-gasdynamic system of equations, energy input, channel flow, Richtmyer–Meshkov instability.
