Abstract

This work investigates the influence of slip boundary conditions on modal stability analysis of compressible Couette flow at two distinct Mach numbers. Slip boundary conditions are extracted directly from kinetic gas theory, using Direct Simulation Monte Carlo, and are applied to the ordinary differential equations governing compressible Couette flow. Modal stability analysis shows only qualitative differences between least stable eigensolutions for the respective cases with and without slip boundary conditions. This is in good agreement with findings of a similar study conducted for hypersonic boundary layers by Klothakis et al. (Theoretical and Computational Fluid Dynamics 36, 117-139, 2022).
