| Abstract: | In this paper, the problem of inner flow around three cylinders is investigated by using boundary element method. The velocity and pressure field in the domain and the distribution of boundary pressure are computed. In order to enhance the computing accuracy, the mingle unit method is applied at the angle-points. Some numerical examples are given to validate the presented method. |
