Pressure based flux-split solutions for incompressible and compressible internal flows (Q1390161)

We present two primitive variable, pressure based, flux-split, reduced Navier-Stokes (RNS) solution procedures for viscous flows. Both methods are uniformly valid across the full Mach number range, i.e. from the incompressible limit to high supersonic speeds. The first method is an `optimized' version of a previously developed global pressure relaxation RNS procedure. The second method is a time-marching `linearized' convection RNS/NS procedure. Both formulations are robust and provide accurate solutions for a variety of internal viscous flows.
