一、前言 燃油浓度分布与气动特性是决定发动机燃烧室性能的两个关键。试验结果表明,实际燃烧室中,流体速度的不均匀性与温度对燃油浓度分布的影响均需考虑。本文在试验研究基础上,介绍了非均匀高速热气流中跨流喷射的两态燃油浓度分布的计算方法。 First, the foreword Fuel concentration distribution and aerodynamic characteristics of the engine combustion chamber to determine the performance of the two key. The experimental results show that, in the actual combustion chamber, the influence of the fluid velocity inhomogeneity and temperature on the fuel concentration distribution should be considered. Based on the experimental study, this paper introduces the calculation method of the cross-flow injection of two-state fuel concentration distribution in non-uniform high-speed hot gas flow.
