Experimental study on propagation characteristics of rotating detonation wave of liquid kerosene with oxygen-enriched air

Abstract In order to study the propagation characteristics of rotating detonation wave (RDW) liquid fuel, an experimental was carried out with kerosene at room temperature as fuel and oxygen-enriched air oxygen volume fraction 38.5% oxidant in this paper. RDW equivalence ratio range 0.65~0.9 successfully obtained by controlling mass flow, a detailed analysis out. The results show that increase ratio, state gradually changes from premature flameout discontinuous complete operation continuous detonation. flow blockage injectors will further worsen mixing effect under low conditions, resulting phenomenon repeated flameout-initiation process combustion chamber. study, almost all waves operate two-counter mode, except there is single mode short period after process.
