Numerical and boundary condition effects on the prediction of detonation engine behavior using detailed numerical simulations

Frontiers in Aerospace Engineering, 2023
High-fidelity numerical simulations of an experimental rotating detonation engine with discrete fuel/air injection were conducted. A series of configurations with different feed-plenum pressures but with constant equivalence ratio were studied.
