Abstract
Upwind schemes have been evaluated for their accuracy based upon steady-state solutions of Euler and Navier–Stokes equations. It includes the flux-vector splitting schemes due to Steger–Warming and Van Leer, flux-difference splitting schemes due to Roe and Osher, and the hybrid schemes, AUSM (Advection Upstream Splitting method) and HUS (Hybrid Upwind Splitting). Computations for inviscid and viscous compressible flows that are well documented in literature have been carried out in a unified framework. Comparisons of lift, drag, skin-friction and heat-transfer coefficients have been established with reference computational and experimental results.
