Technical Note— Hydrogen combustion in a hypersonic airstream

Abstract

An experimental and computational investigation of hypervelocity, hypersonic combustion of hydrogen with air is described which was intended to confirm the presence of combustion at these conditions and then to gauge the pressure rise associated with the heat release of combustion. Experiments were conducted in a square cross section duct and wall pressure was measured. It was found that combustion did occur and that the maximum pressure increase was approximately 72% over the intake pressure.
