Abstract

A comprehensive experimental and computational study of the shock detachment process in hypervelocity flow over cones is presented. The experiments are carried out in the T5 hypervelocity shock tunnel. The computations are mostly done with a code for axisymmetric thermo-chemical nonequilibrium flow. The data obtained confirm a previous theoretical model that predicts lower growth rate of the detachment distance with increasing cone half-angle for nonequilibrium flows than for frozen and equilibrium flows. The lower growth rate is related to the behavior of the sonic line in relaxing flows. The growth of the subsonic region is studied in detail from attached to detached conditions. A comparison between measured and computed interferograms is also made. Measured and computed heat flux distributions are compared, and differences between flows with attached and detached shocks are discussed.
