| 摘 要： | 本文应用商业软件FLUENT进行数值模拟。首先将静止圆柱和旋转振荡圆柱绕流的计算结果与文献18]进行了比较,接着对典型二维翼型沉浮振荡的计算结果与实验图像进行了比较,以此验证了用Fluent软件计算非定常运动的可靠性。在此基础上,本文对二维翼型沉浮、俯仰以及沉浮/俯仰联合运动这三种方式分别进行了模拟,分析了不同参数如振幅、频率、沉浮和俯仰之间的相位差的影响。得出一些有意义的结论和新的现象。

| Abstract: | In order to verify the software FLUENT credible and accurate, the calculated results of the flow around a static and a rotary oscillating cylinders are compared with the results of Ref.\ and the numerical results of the flow caused by a 2D airfoil in heaving motion are compared with the experiments. The three different motion of 2D airfoil such as heaving, pitching and heaving/pitching combined are simulated, respectively, in this paper. The effects of the amplitude and frequency of the oscillation, the phase difference between the pitching and heaving are also discussed. |
