A numerical analysis using a CFD code specifically designed for hypersonic flows has been performed by modelling external supersonic combustion of hydrogen and ethylene fuels with hypersonic air flow at Mach 7.6. In comparison with the Coras-Paull [1,2] experimental data from the University of Queensland shock-tunnel, the results indicate good correlation of the relative pressure increase on fore (intake) and aft (thrust) surfaces due to fuel injection with and without combustion. For the geometry considered, air by itself results in an increase in the net drag force. With fuel injection and combustion the drag force increases further. Ethylene injection for several inflow conditions did not yield stable combustion, but only caused an increase in the drag force.
