摘要：
To investigate the influence of inlet parameters on plasma ignition processes, the chemical reaction of plasma ignition and the change in flow field were numerically simulated after establishing a numerical calculation model of the plasma ignition combustion. Then the influence of jet velocity, jet temperature and mixed gas's inlet velocity on the plasma ignition process was analyzed. The calculation results show that, when high temperature plasma jet gets into the combustion chamber, the combustion region extended to the upstream is much larger than that to the downstream, and stable combustion forms in the upstream firstly. The effect of plasma jet velocity on ignition delay time is relatively small, but the increase of jet velocity can enforce the plasma jet's penetration ability. The mixed gas's ignition delay time increases with decreasing jet temperature and increasing inlet velocity of the mixed gas.
