Stabilities of Rotating Detonation Waves

Abstract

Revealing the physical mechanism underlying the stability of rotating detonation waves could significantly advance the development of detonative propulsion technologies. Our laboratory has focused on this issue and developed advanced high-fidelity numerical strategies for simulating compressible two-phase reactive flows. We have conducted research on complex wave propagation in an annular combustor, fueled by kerosene spray, elucidating the evolution of wave configurations and exploring their stabilities. The experimental observations were carried out to validate our numerical findings in rotating detonation combustors. This analysis can provide valuable insights for colleagues engaged in research on two-phase detonation combustion.
