Simulating Argon, Helium, and Nitrogen Shock Waves

Abstract

We simulate the structure of the shock wave front in the range of Mach numbers from 1.5 to 10 using quasigasdynamic (QGD) equations and Navier - Stokes (NS) equations. The numerical results are compared with published experimental data. QGD and NS calculations produce close results that tightly fit the experimental data, especially for the monatomic argon and helium. The QGD algorithm is found to be more stable than the NS algorithm.
