| 摘 要： | 文献1]提出求解流场中物体附连水质量的边界元算法，对于无限域流场，只需对物体表面进行边界单元离散．在此基础上，通过映象法和迭加原理修改Laplace方程的基本解，将该方法推广到半无限域流场的情况，适用范围更广．最后给出几个典型箅例，通过结果对比表明方法的有效性．

| Abstract: | A boundary element method for solving added mass of structure embedded in infinite liquid field was presented in Ref. 1] where only surfaces of the structure need to divide into the boundary elements. This method is extended to the semi-infinite liquid field problems, which has a wider application in engineering, by modifying the fundamental solution of Laplace equation using mirror method and superposition method. Finally several typical numerical examples are given to illustrate the efficiency of this method. |
