A stable and conservative high order multi-block method for the compressible NavierStokes equations ?
A stable and conservative high order multi-block method for the time-dependent compressible NavierStokes equations has been developed. Stability and conservation are proved using summation-by-parts operators, weak interface conditions and the energy method. This development makes it possible to exploit the efficiency of the high order finite difference method for non-trivial geometries. The computational results corroborate the theoretical analysis.
