Two-dimensional numerical investigation on the gas-liquid two-phase rotating detonation waves
To study the detonation characteristics of gasoline-air two-phase rotating detonation engine (RDE),the two-dimensional two-phase unstructured triangle Conservation Element and Solution Element method (CE/SE method) is used to calculate the governing equations.The physical model of the RDE and the chemical reaction model are proposed.The calculation results validate that the unstructured CE/SE method can capture the rotating detonation waves(RDW) effectively.In the ignition process, the strategy of the hot jet ignition is used to ignite the rotating detonation engine.The fresh fuel mixture layer can preserve the detonation wave from decoupling and extinguishing, which is the key to forming the RDW quickly.The flow field of the stable gas-liquid rotating detonation waves is obtained.The peak pressure and temperature of gasoline-air RDW are 4.0MPa and 2800K respectively.
