A comparative evaluation of, upwind schemes for compressible Euler and Navier-Stokes equations

Abstract

Issues involved in the comparative evaluation of upwind schemes for Euler and Navier-Stokes equations have been addressed. Apart from accuracy. these include robustness and computational efficiency attained in the presence of convergence acceleration devices. A survey of upwind schemes and convergence acceleration devices is presented. A selective study based on a comparison of accuracy for Roe and Osher schemes has been conducted till unified framework. Computations in subsonic. transonic, supersonic and hypersonic regimes have been carried out and comparisons of lift, drag, skin-friction and heat-transfer coefficients with reference solutions have been ported.
