The dependence of the breakdown topology on the shock‐vortex interaction conditions is numerically investigated. Based on solutions of the Euler equations the unsteady three‐dimensional flow field is studied at several freestream Mach numbers and for normal and oblique shocks. The results of the finite‐volume method using the AUSM approach indicate a strong dependence of the recirculation region downstream of the shock on the shock induced pressure gradient and on the vortex strength.
