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.
