Abstract

The flow field behind a detached shock wave, created by a blunt body in a supersonic air stream, is analyzed with respect to energy dissipation through the action of viscosity in the fluid stress field near the axis of symmetry. This energy dissipation is related to the rise in entropy, and consequently to the additional drop in reservoir pressure beyond that given by the Rayleigh pilot tube formula. The method is applied to the calculations of an apparent defect in reservoir pressure, for more precise calculations of free stream Mach numbers using total head tube measurements.
