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 high-order accuracy Godunov scheme and the time correlation method are used to solve the unsteady Euler equations with viscous force on the full flow S2 flow field of a small turbofan engine using a multi-component model. The simulation results and tests The results are compared. When the loss is reasonably given, the calculated results are in good agreement with the experimental results.
