Forward-Facing Step

Supersonic flow past a forward-facing step.

In this section we present the numerical results for the forward facing step test problem made famous by Woodward and Colella. The initial flow field is at Mach 3 and a polytropic ideal gas is adopted. The step size is 20 per cent of the inlet.
