| 摘 要： | 在二维非牛顿流体流动分析的基础上，根据高弹粘流在狭缝流道中流动的特点，建立了一种半数值解析有限元法——有限块法。该法可将三维流动问题化为平面问题处理，具有节约内存与机时，使用方便等优点。通过算例证实，该法可用于工程中使用的一般流道，且解的精度令人满意

| Abstract: | Numerical simulation of the flow of highly viscoelastic flow in three dimensional slit channels has been carried out by FBEN which was developed in this paper according to the lubricanting approximation theory. FBEM can change three dimensional problem to two dimensional. It is proved through a comparison with analytic solution that FBEM possesses higher accuracy and only needs less space and CPU in computation. |
