摘要
应用高收敛率、高精度和高分辨率的数值计算方法，通过求解非定常、可压缩雷诺平均的Ｎａｖｉｅｒ—Ｓｔｏｋｅｓ方程和ｑ-ω低雷诺数双方程湍流模型，数值预测了Ｓ８０９翼型在０－７０°攻角范围内大尺度分离与失速流场的流动与损失特性。
Numerical simulation of two-dimensional flow fields is presented for the NREL (NationalRenewable Energy Laboratory) S809 airfoil. The flow is modeled as compressible, viscous,steady/unsteady and turbulent. The fourth--order higher resolution MUSCL TVD schemeand new LU-type implicit scheme are used for solving the Reynolds--averaged Navier--Stokesequatons and q-ω. low-Re yn o ld s-un mb e r two--e qu at ic n t urb ule nc e mo de l. T he I ar ge-s c al eseparated flow fields and their losses at the stall conditions are analyzed for the NREL S809airfoil at various angles of attack from 0 to 70 degrees.
