Abstract
In order to study the flow field of gas-liquid two-phase rotating detonation engine, a Eulerian-Lagrangian model of unsteady two-phase detonation was established. Using the SST (shear stress transport) k-ω model and the chemical reaction model based on the one-step reaction mechanism, the two-dimensional non-premixed numerical simulations of kerosene and air rotating detonation engines were carried out. The results showed that the droplet particles of 30 μm were atomized, broken, evaporated and mixed in the air flow at the total inlet temperature of 1 000 K, and a stable single rotating detonation wave was formed within the equivalence ratio range of 0.70 to 1.15. The kerosene droplets were not completely burned by the detonation wave, and a part of the kerosene was mixed in the high temperature products and discharged downstream. Near the inlet of combustion chamber, the air triangle formed in front of the detonation wave was larger than the droplet triangle.
