摘要: 本文提出了一种计算尖角拐角点附近微小区域涡度的方法。该方法与Roache提出的几种方法进行了比较。对Cavity模型进行了数值计算,结果显示了新推荐方法处理奇异性问题的有效性。

Abstract: An algorithm to compute vorticity of the micro area around the sharp turning points is developed. The comparison between the proposed method and the methods developed by Roache is given. The paper also presents the numerical tests on cavity model and the results show the efficiency of the proposed method in treatment of the singularity problem.
