| 摘 要： | 本文用涡团法模拟了有限平板的绕流问题,计算出一个长度为1的无穷薄平板在静止的流体中突然起动并作匀速运动的周围流场的变化情况。方法上,用保角变换解决了在涡团法中遇到的一个拉普拉斯方程,并对变换中的奇点作了特殊处理,最后得到一个与已有的实验结果完全吻合的周期性数值解。

| Abstract: | The flow past a finite flat plate is simulated numerically by vortex method in this paper. The velocity field is calculated around the flat plate with length 1 which started impulsively with a constant velocity.A Laplace eguation appeared in vortex method is solved by conformal transformation.The singular points in the transformation are treated specially,finally, we obtain a periodic numerical solution which agree quite well with the experimental results. |
