Abstract
The flow fields associated with Mach reflection wave configurations in steady flows are analysed, and an analytical model for predicting the wave configurations is proposed. It is found that provided the flow field is free of farfield downstream influences, the Mach stem heights are solely determined by the setup geometry for given incomingflowMach numbers. It is shown that the point at which the Mach stem height equals zero is exactly at the von Neumann transition. For some parameters, the flow becomes choked before the Mach stem height approaches zero. It is suggested that the existence of a Mach reflection not onlydepends on the strength and the orientation of the incident shock wave, as prevails in von Neumann's threeshock theory, but also on the setup geometry to which the Mach reflection wave configuration is attached. The parameter domain, beyond which the flow gets choked and hencea Mach reflection cannot be established, is calculated. Predictions based on the present model are found to agree well both with experimental and numerical results.
