Low-Order Model for Detonation Velocity Suppression in Rotating Detonation Combustors
AIAA SCITECH 2023 Forum, 2023 A Rotating Detonation Combustor (RDC) is a novel pressure gain combustion device, in which a detonation wave processes steadily around an annulus. It has been experimentally observed that detonation waves in the RDC propagate slower than the idealized Chapman- Jouguet (CJ) speed (as low as approximately 60%) and with lower than expected peak pressures.
