| 摘 要： | 从变比热容角度出发，采用ＣＦＤ方法计算了发动机加力工作时高温状态下喷管内部流场分布和性能，并和定比热容计算结果进行了比较。结果表明，采用ＣＦＤ方法计算加力工作时喷管内部流场和性能，应该考虑变比热容的影响。

| Abstract: | With high temperature in engine nozzle , the effect of variable specific heat on nozzle flow field and perforance should be considered A algorithm based on solving Navier-Stokes equations with variable specific heat was developed to solve this problem The results with variable specific heat were compared with those considering constant specific heat The results show that the method of solving Navier-Stokes equations with variable specific heat is effective to calculate the nozzle flow fields and performance |
