Abstract : This research investigates the effects of inlet dump angle on the size, shape, location and magnitude of recirculation zones for single side dump Pulse Detonation Combustor detonation tubes and describes the methods and results of hypothesized improvements to the internal flow path of those engines to ensure complete inter-cycle quenching. Additional analysis was conducted to visualize the dispersion of fuel along the feed tube and into the dump region as a means of providing initial validation of the design with respect to appropriate fuel concentration within the geometry.
