Abstract: Through comparing different results of simulating shock reflection flow over a forward step using different schemes including Roe and van Leer schemes,the advanced upwind scheme (AUSM+) is fully studied in terms of its resolution and efficiency for shock waves,expansion vaves,contact discontinuities and their interactions.Its advantages of low numerical dissipation and high resolution for discontinuities are demonstrated.

Key words: AUSM+, upwind scheme, shock reflection, limiter
