Generating Detonation Waves in an Annulus via Phased Adiabatic Shocks

Abstract

This thesis documents the design and development of a continuous rotating detonation combustor. The design of the combustor incorporates a new system to initiate and control detonation waves within an annular duct. This system known as the wave controller functions by generating phased adiabatic shocks using an azimuthal array of spark plugs. The main intent of the research was to determine the effectiveness and usability of the wave controller in developing transverse waves to initiate a detonation wave. Imaging data of the adiabatic shocks in the annulus was obtained using a high-speed camera and optical setup. The data presented here illustrates the wave controller’s capability in creating transverse shock waves traveling circumferentially. Another aspect of the research is to introduce a new injection scheme and provide experimental results on its effectiveness in mixing fuel and oxidizer.
