ON THE HYPERSONIC LEADING-EDGE PROBLEM IN THE MERGED-LAYER REGIME,

Abstract

Finite-difference analyses are applied to a single set of partial differential equations derived from full Navier-Stokes equations under a thin-layer approximation for the entire flow field (including the shock-like region). Solutions obtained for the caloric perfect gas are compared with available data from air and nitrogen experiments. Calculated values for heat-transfer appear to be higher than measured data; examination indicates that certain nonequilibrium effects (rotational de-excitations in particular), unaccounted for in data correlation and in the analysis, may be important sources of the discrepancy.
