Abstract:
The process of flame-out in two kinds of flame-resident ramjet combustor,centerdump and side-dump combustor，were analyzed numerically at the assumption of quasi-steady state． The difference of flow field and the change of flame were discussed when the combustor works closely to the limits of pressure and kerosene concentration．It is found that flame front of center— dump combustor shrinking during the extinguish process．The side-dump combustor has a difference in the temperature of backflow region，which leads to the lose of flameholding．
