Firstly, within the region of pulse interference, the flow field changes periodically. Secondly, the fuel mass flux of pulse jet is only a half of the steady jet in the pulse period, but the the amount of hydrogen combusted even larger, and the total pressure recovery coefficient is greater. Finally, the high temperature pulse injection scheme has a promoting effect on fuel mixing and combustion.
