Experimental Investigation on the Ignition Process of the Evaporative Flame Holder Under the Subatmospheric Pressure
The effects of inlet pressure,temperature,and Mach number on ignition flame evolution characteristics and ignition delay time of evaporative flameholder under subatmospheric pressure were investigated experimentally.The results indicated that increasing inlet temperature would increase the flame projected area and flame growth rate and reduce the ignition delay time.The decreasing trend of ignition delay time will weaken with the temperature increase.Besides,the increased inlet pressure leads to an increased flame projected area and decreased ignition delay time.Then,a first increasing and then reducing trend of flame growth rate and flame projected area was achieved by the increased Mach number.
