Abstract:
Results of an experimental study of continuous detonation of a hydrogen-air mixture in a flow-type annular combustor $306$ mm in diameter in the regime of air self-ejection are reported. The regime of pulsed detonation is also obtained. Stable regimes of continuous detonation with one and two transverse detonation waves having velocities $D = 1.48-1.16$ km/sec are observed in experiments. The frequency of the pulsed detonation wave is $\approx1.4$ kHz. The known condition for the continuous detonation regime (good mixing for the formation of a detonable layer) is validated. The size of the slot for air ejection, providing a necessary flow rate for detonation and a necessary ratio of the species in the mixture, is determined. Some methods for estimating the air flow rate are presented.
