Secondary shock wave in rotating detonation combustor
Aerospace Science and Technology, 2019Abstract The secondary shock wave in rotating detonation combustor is studied by the combination of numerical simulation and experiments. Based on the pseudo-nozzle flow in the post-detonation zone, the influencing factors which cause the existence of secondary shock wave are clarified and then verified by experiments.

Secondary waves dynamics and their impact on detonation structure in rotating detonation combustors
Shock Waves, 2021In this work, we experimentally investigate secondary waves in rotating detonation combustor (RDC) operation. Secondary waves are finite-strength periodic perturbations of the field, which manifest as reacting fronts and/or pressure rise rotating around the annulus superimposed to one or more detonation waves.
