摘　　要：采用了边界元方法 ,对三椭圆柱体的绕流流场和压力场进行了研究 ,在计算时为了避免角点处法线不连续性现象的发生 ,采用非协调单元法对角点进行了处理 .给出了三椭圆柱体的绕流流场和压力场 .The problem of flow field and pressure field of the flow around the three-elliptic cylinder are studied by using Boundary Element Method.We also use Incompatible Element Method in order to avoid discontinuity of normal direction,in sharp sections of boundary.In this paper,we give not only the flow field but also the pressure.

关 键 词：压力场 流场 阻力
