Direction Control of Rotating Detonation Waves with Helical Combustion Chambers

Journal of Propulsion and Power
This paper explores the innovative direction control of rotating detonation waves in rotating detonation engines (RDEs) by adjusting the ignition location and employing helical combustors with a sinusoidal cross section. In our experimental setup, we conducted 25 combustion tests using two distinct combustor geometries, each featuring different ...

Experimental Study of Instabilities in Hydrogen-Air Fueled Rotating Detonation Combustion

ASME 2024 Power Conference
Abstract Conventional gas turbine engines rely on an idealized constant pressure combustion process that in reality produces a pressure decrease as a result of viscous and other non-reversible losses. An alternative approach is rotating detonation combustion (RDC) which is a form of pressure gain combustion in which one or more ...

Parametric Influence on Rotating Detonation Combustion: Insights from Fast Reactive Euler Simulations

AIAA Journal
A two-dimensional unsteady reactive Euler solver is employed to model rotating detonation combustion (RDC). A baseline case is chosen, and several combustor geometric and design parameters are varied individually in order to assess their effect on flowfield structure, exhaust flow properties, and performance.
