中文摘要：

利用计算流体力学软件STAR—CCM＋对奥运会比赛用帆板及帆船帆翼的空气动力性能进行了数值模拟，得到了不同攻角下的帆翼在粘性流场下的数值模拟结果和相应的升力系数及阻力系数。对不同攻角下的升力系数和阻力系数计算结果与实验结果进行了对比，通过比较可以看出利用STAR—CCM＋软件能够快速有效地预报帆翼空气动力性能和流场。

英文摘要：

In this paper, the aerodynamic performance of the sail of windsurfer and sailing boat which is used in the Olympic Games in full scale was simulated based on the computation fluid dynamics commercial software STAR-CCM＋. The numerical results of the lift coefficient and the coefficient of drag at different angle of attack were obtained. The computation of the lift coefficient and the coefficient were compared with the trial results. The validity of the calculation of the software to predict the three-dimensional viscous flew and aerodynamic performance of the sail was proved.
