为研究应用于全流量补燃循环发动机的不同气／气喷嘴得到的燃烧流场，通过求解 Navier－Stokes方程组，对不同燃料与氧化剂速度比下的流动燃烧过程进行了数值计算，计算结果与实验结果吻合。仿真结果表明：增加速度比能使燃烧火焰面提前，燃烧效率变大。如果发动机的长度受到限制，可以适当增加速度比以实现高效燃烧。

In order to investigate the combustion flow field of gas/gas injector in full-flow staged combustion cycle engine,the flowing combustion processes of different velocity ratios between fuels and oxidants were numerically simulated by solving the Navier-Stokes equations. Simulation results which agree well with the experimental results show that:the combustion efficiency increases and the combustion flame surface advances along with the increase of velocity ratio;if the length of the engine is restricted,the effective combustion can be achieved by increasing the velocity ratio appropriately.
