The three-dimensional potential flow inside the impeller of a screw centrifugal pump was analysed by the boundary element method.
采用边界元法对螺旋离心泵叶轮中的三维势流进行了数值计算。

Oil migrated from higher potential belts to lower ones in "centrifugal flow", which was the regional dynamic condition of controlling petroleum accumulation and distribution.
油气由高势区向低势区呈“离心”式运移，这正是控制油气呈环、带状聚集与分布的区域动力学条件。

The main difficulty of numerical solution for two-dimension potential flow in a centrifugal scroll is how to determine the branched streamline.
