STAGNATION POINT HEAT TRANSFER IN HYPERSONIC HIGH ENTHALPY FLOW.

Abstract

This paper describes stagnation point heat transfer measurements at a range of enthalpies relevant to re-entry speeds using the Australian National University Free Piston Shock Tunnel, T3. The test gases used were air and carbon dioxide and the present measurements extend the database of Miller et al. The results show that pronounced non-equilibrium in the shock layer results in reduced convective heat transfer rates. This is consistent with earlier theoretical calculations and similar measurements. Show more
