摘　　要：介绍了大湿度燃烧计算模型及STIG燃烧室流场计算的数值方法,并就不同蒸汽喷注方式对燃烧室流场特性的影响情况进行了广泛的数值模拟研究,得出了一些规律性的结论。A humid combustion computation model is introduced and some numerical research is carried out on the STIG combustor inner flowfield characteristics under different steam injection schemes. It is proven that the installation position of steam injectors is the most important factor on flowfield characteristics and it is recommend to install them shortly after the back flow zone. Increasing the velocity and flowrate of the injected steam will strengthen the influence and it will be more beneficial if distribute the injectors more equally on the combustor wall.
