N2 - The numerical dissipation of four types widely used upwind schemes (the Roe, the van Leer, the AUSM family and the CUSP type) were studied by solving Euler equations. Two-dimensional complicated flows were simulated in various Mach number range in steady/unsteady state. The first-order solution, which revealed the sheer accuracy of a scheme, was presented in order to eliminate the flux limiter effect. The results show that the CUSP type has the largest numerical dissipation of all the schemes and the AUSMDV scheme comes second. The AUSMPW and the AUSM+UP have the strongest shock capturing capability, while the AUSMDV has the worst performance.
