通过数值模拟和实验研究了空气节流对乙烯燃料超燃冲压发动机燃烧室火焰稳定性的影响。在马赫数为2.0、总温度为900 K、总压为0.8 MPa、总当量比为0.5的入流条件下，得到了上述结果。空气节流产生的激波序列对超燃冲压发动机燃烧室的流动结构有很大影响。与未进行空气节流的燃烧室相比，经过空气节流的燃烧室流场速度更低，压力、温度和涡流强度更高。空气节流是实现火焰稳定的有效途径；没有空气节气装置的燃烧室燃烧几乎爆裂。实验中，节流位置为745 mm的燃烧室燃烧接近井喷，节流位置为875 mm的燃烧室内燃油/空气混合气燃烧强烈。空气节流的位置和时间顺序的选择对燃油点火和火焰稳定至关重要。数值模拟结果与实验结果吻合较好。
The effect of air throttling on flame stabilization of an ethylene fueled scramjet combustor was investigated by numerical simulation and experiments in this paper. The results were obtained under the inflow condition with Mach number of 2.0, total temperature of 900 K, total pressure of 0.8 MPa, and total equivalence ratio of 0.5. The shock train generated by air throttling had a big effect on the flow structure of the scramjet combustor. Compared with the combustor without air throttling, the flow field with air throttling had a lower velocity and higher pressure, temperature, and vortices intensity. Air throttling was an effective way to achieve flame stabilization; the combustion in the combustor without air throttling was nearly blowout. In the experiment, the combustion was nearly blowout with air throttling location of 745 mm, and the fuel/air mixture in the combustor with air throttling location of 875 mm was burned intensively. It was important to choose the location and time sequence of air throttling for fuel ignition and flame stabilization. The numerical simulation results agreed well with experimental measurements.
