✦ Synopsis

In this paper, 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.

In this paper, alternative formulations of the steady Euler equations for conservation of mass, momentum and energy are adopted for the numerical simulation of compressible ¯ows with shock waves. The total enthalpy is assumed to be constant and hence an isentropic density is calculated in terms of t
