Simulation of steady compressible flows based on Cauchy/Riemann equations and Crocco's relations. Part II. Viscous flows

Abstract

An alternative formation of the Navier-Stokes equations is used for steady compressible fluid flows. Two scalar equations are solved for the total enthalpy and entropy respectively, and a system of equations is solved for the velocity components. The latter consists of the continuity equation and the definitions of vorticity. Numerical results for two-dimensional low and high Reynolds number flows are presented and compared with standard calculations. The advantages of the present formulation are briefly discussed
