Abstract

An efficient pressure-based algorithm to solve the compressible Navier-Stokes equations at low Mach numbers including the limiting case of fully incompressible computations is developed in the present work. The algorithm is based on two-scale splitting of the pressure into the volume-averaged and dynamic parts and uses the full Navier-Stokes equations without any reductions or preconditioning in order to study flows at all speeds.
