Abstract
The effect relative motion between a shock and supersonic flow has on the Mach number of flow behind a planar shock is considered. It is shown that for multiple moving reference frames, such as that encountered in a shock-wave/moving-body interaction the choice of reference frame can result in a Mach number that can either increase or decrease across the shock. This depends on the relative velocities of the reference frames and under certain conditions can remain unchanged for a given shock of finite strength. Euler simulations run at the various computationally predicted transitions have numerically confirmed the idealised analysis presented here.
