Pressure based calculation procedure for viscous flows at all speedsin arbitrary configurations

Abstract

A calculation procedure for viscous flows at all Mach numbers has been described. The scheme has been developed for a nonorthogonal coordinate system. In order to handle both incompressible and compressible flows, pressure has been selected as a primary dependent variable in preference to density. The pressure field is evaluated using the compressible form of the SIMPLER algorithm. The accuracy of the proposed scheme has been assessed by comparing the results with experimental data or other numerical results available in the literature.
