Abstract
The turbulence combustion was induced by arranginga orifice plate on the flame propagation path. The effect of initial temperature on induced turbulence combustion characteristics of pre-mixture hydrogen-air was studied by the high-speed schlieren photograph system and pressure data acquisition system. The experimental results show that the flame spreads down slightly before the flame passes through the orifice plate, and then is induced into turbulent combustion which accelerates the flame development maximum pressure rise rate decrease in advance, and the change rate of the combustion duration reduces after the addition of the orifice plate, but there is no significant difference in the flame propagation speed after the flame passes through the orifice plate.
