The impact of film cooling on the heat release within a rotating detonation combustor
Applications in Energy and Combustion ScienceRotating detonation combustors establish a detonation wave that continuously circulates inside a small annulus. The presence of the detonation wave and the downstream oblique shock within the small annulus coupled with high mass flow induces a high heat ...
