摘要
采用高阶精度Godunov格式和时间相关法,用多部件模型在小型涡扇发动机的全流道S2流面上求解带黏性力项的非定常Euler方程组,并将整机模拟的结果与试验结果进行了对比,在合理给出损失的情况下,计算结果与试验结果基本吻合。
The flow passage of a small turbofan engine is simulated by use of the multi- component model. The unsteady Euler equations with viscous loss items on S2 surface along the engine flow passage are solved by utilizing the Godunov＇s high order accuracy program and time matching method. The results are in accordance with the test data with proper loss model provided.
