A Numerical Study of Interfacial Instabilities at High Mach Numbers
In the present study we perform direct numerical simulations of high Mach number shear flow instabilities based on the two-dimensional Navier-Stokes equations. To deal with the steep gradients and shocks which emerge after the growth of instabilities we employ modern high resolution shock capturing schemes. We point out some peculiarities arising generally when shock capturing schemes are applied to shear flow stability problems in the limit of vanishing viscosity. Streaklines are calculated to visualize the development of the instabilities.
