12.So it is of very important science meaning and practice value to simulate the circle flow field of the ramjet shell. 因此,对冲压增程炮弹绕流流场的研究具有重要科学意义和实用价值。 13.Advanced ramjet technologies are also important for scramjet development, and the Chinese have been active in ...
Increasing the overall equivalence ratio decreased the transition duration, but had no significant effect on the dynamics of this process. The results suggest that thermal choking due to wall heating downstream of the cavity drives the scramjet to ramjet mode hopping, while flame quenching and blow-...

Demonstration of Mode Transition in a Scramjet Combustor Recently, tests were performed in which the flow rates were systematically varied during the test to simulate an acceleration from M = 5.9 to 6.2. ... SULLINS,A G. - 《J.propul.power》 被引量: 101发表: 2011年 Integral booster/ramjet...
TransitionRegion of inoperabilityCombustor-Isolator interactions during scram to ram mode transition in a hydrogen-fueled scramjet combustor are numerically investigated at an operating Mach number of M=2.17. The twodimensional flow domain is modeled based on the isolator and combustor sections of a ...
Experimental study on combustion mode transition effects in a strut-based scramjet combustor A strut-based scramjet combustor was operated in three different combustion modes under Mach 2.5 inflow conditions, scramjet mode, weak ramjet mode, and st... Qingchun,Yang,Jichao,... - 《Proceedings of ...
Although the first two combustion modes of this case were similar to those of the case with d / H = 2.0 , a new combustion mode (unsteady jet-wake stabilized scramjet mode) was observed in this case. The mode transition between the cavity stabilized scramjet mode and the unsteady jet-wake...
