An extension of the immersed interface method developed by Brehm and Fasel1-3 to the compressible Navier-Stokes equations is presented. The extension of the immersed interface/boundary method1,2 contains some modifications to the original approach in order to incorporate characteristics of the compressible Navier-Stokes equations. The van Leer flux splitting approach utilized in the compressible Navier-Stokes solver was considered in the design of the finite difference stencils in the vicinity of the immersed boundary. The extensive stability investigations of the immersed scheme confirm that a stable immersed boundary treatment is achieved. The simulation results for a Mach 6 boundary layer flow over a flat plate and a porous wall validate the proposed immersed boundary method for the compressible Navier-Stokes equations.
