| Summary: | Detonation waves propagate at velocities exceeding 1 000 m/s, enabling the reactants to complete reaction without significant expansion, thereby an isochoric combustion process can be achieved. Consequently, it has a great potential for enhancing thermodynamic cycle efficiency. As a feasible approach, rotating detonation has received extensive attentions in aerospace propulsion. This work analyses progresses in liquid-fueled rotating detonations, including the ignition and initiation process, the effects of oxidizer and fuel preprocessing on propagation the detonation wave under ambient temperature conditions, and the efforts of achieving rotating detonations in a ramjet and an afterburner under high-enthalpy inflow conditions. Finally, the prospects of utilizing rotating detonations for propulsion applications are discussed. |
