摘要：

The paper presents some aspects about how to treat the integrals of singular kernels in case of solving 3D problems of fluid flow. An efficient method that can be applied consists in using suitable geometrical transformations of coordinates to eliminate the singularities. To show the effectiveness of this method we apply the technique to the problem of compressible fluid flow around an obstacle in three dimensions. The boundary mesh is obtained by using triangular linear isoparametric boundary elements. A computer code based on this method is made and numerical results are obtained. The computer code is tested by making an analytical checking and the results show the efficiency of the method.
