The Propagation Characteristics Of A Detonation Wave In A Supersonic Flow

Abstract

This paper establishes the investigation of a propagating detonation wave from a pre-detonator into a supersonic crossflow. The current Mach 5 high-enthalpy combustor provides a supersonic quasi-premixed stream targeted to match the CJ detonation conditions for a propagating detonation. The detonation wave is initiated by a hydrogen-air pre-detonator that then can propagate orthogonally through the 45x45mm channel feeding the supersonic combustible mixture. High speed Schlieren and pressure measurements are utilized to outline the detonation wave transfer from the pre-detonator to the supersonic flow and visualize the evolution of the detonation through the supersonic flow.
