摘要
进行了多级跨音速风扇粘性流动的数值模拟研究。求解全三维 N-S方程 ,通过高分辨率格式提高跨音速流场计算的准确性 ,利用 LU-SGS隐式解法加快计算收敛速度。给出了一双级高负荷跨音速风扇设计和非设计工况下的详细计算结果 ,各工况下的计算与实验数据均吻合较好。
Numerical simulation of viscous flows through multistage transonic fans was carried out. Three dimensional Navier\|Stokes equations were solved. The accuracy was improved with a high\|resolution scheme. And the convergence was speeded up by the use of LU\|SGS implicit method. The computed results for a highly loaded two\|stage fan at design and off\|design conditions were given in detail. The simulation results show good agreement with experiment data.
