摘　　要：研究了绕两柱体的内流问题 ,采用了流体力学边界元方法〔1〕.为了提高计算精度 ,在对边界积分离散化计算时 ,增大了单元的密度 ,并对角点问题用非协调单元法进行了处理 ,得到了速度场和内点的压力分布 .结果合理 。In this paper,we use the fluid mechanic boundary element method.The problem about inner flow around two cylinders are researched.In order to improve the precision of calculation,the density of unit is enlarged when we calculate the boundary integral discretization,as well as the problem about angle-point is conducted using uncoordinate unit method.The velocity field and press distribution of inner point are acquired.The result is reasonable and the method is valid.

关 键 词：边界元方法 流场 压力分布
