| 摘 要： | 以ＬＵ－ＴＶＤ混合格式求解二维非定常湍流Ｎ－Ｓ方程，计算了绕１／４弦点振荡的翼型跨音速粘性绕流解，与实验结果吻合较好。通过取不同ＣＦＬ数计算表明：在能得到非定常稳态解的情况下，取小ＣＦＬ数更能真实地反映非定常时间历程，具有更高的可信度

| Abstract: | A LU TVD scheme is applied to calculate the unsteady flow around a pitching oscillatory airfoil. The results given by this paper are in good agreement with experimental results. Application of different CFL numbers show that using less CFL number can describe the unsteady course more detaily and has higher reliability. |

| Keywords: | unsteady flow N S equation airfoil profiles numerical analysis |
