Influence of fuel inhomogeneity on detonation wave propagation in a rotating detonation combustor
Shock WavesAbstractRotating detonation combustor (RDC) is a form of pressure gain combustion, which is thermodynamically more efficient than the traditional constant-pressure combustors. In most RDCs, the fuel–air mixture is not perfectly premixed and results in inhomogeneous mixing within the domain.

Dynamic mode decomposition analysis of rotating detonation waves [PDF]
Shock Waves, 2020 AbstractA rotating detonation combustor (RDC) is a novel approach to achieving pressure gain combustion. Due to the steady propagation of the detonation wave around the perimeter of the annular combustion chamber, the RDC dynamic behavior is well suited to analysis with reduced-order techniques.
