液体碳氢燃料旋转爆震燃烧研究进展

Detonation waves propagate at velocities exceeding 1.000 m/s, enabling the reactants to complete reac-tion 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, inclu-ding 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.
