Research on Ignition process of Ramjet with Cavity-based Flaxneholder

摘要

Research on the ignition process of ramjet with cavity-based flameholder is carried out. Air heater with electrified resistance is employed. The pressure and temperature at the entrance of the combustor is 60KPa and 600K. The ignition and flame spread process is illustrated. Different ignition location is compared to investigate the influence towards ignition process. Cavity with different L/D ratio and aft wall height is tested; the results suggest that small L/D ratio and aft wall of the same height with front wall are favorable for successful ignition.
