摘要

通过求解k-ε湍流模型的Navier-Stokes方程组

对以气氢/气氧为推进剂的同轴双剪切喷嘴燃烧室流场进行数值模拟研究.结果表明:气-气推进剂在燃烧室内形成两个燃烧面

能在大流量下实现较高的燃烧效率;同轴双剪切喷嘴的氧喷注速度和氢氧速度比是同轴双剪切喷嘴设计的关键参数

氧喷注速度越小使推进剂的燃烧位置越远离喷注面

而氢氧速度比越大使燃烧位置越靠前;与气-液同轴剪切喷嘴相比

同轴双剪切气-气喷嘴的设计可以取较大的氧喷注速度和适合的氢氧速度比.

Abstract

The turbulent Navier-Stokes equations in combination with two equation k-ε turbulence models were used to simulate the flow field of shear dual-coaxial single element GO2/GH2 injector chamber.The results show that: the shear dual-coaxial injector has two shear combustion surfaces

enabling to achieve a high combustion efficiency at the condition of large mass flowrate

the oxygen injection velocity and the velocity ratio of hydrogen to oxygen are key parameters for shear dual-coaxial injector design

a lower oxygen injection velocity makes the combustion location far away from the faceplate

while a higher velocity ratio makes the combustion location closer to the faceplate.Compared with the gas-liquid shear coaxial injector

a faster oxygen injection velocity and proper velocity ratio of hydrogen to oxygen are preferable choice for design of shear dual-coaxial injector.
