摘要
文章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，通过将沿流道高度方向流速分布用级数模拟，建立了一种半数值解析法。该法可将三维流动问题化为平面问题处理．且有节约内存及机时，使用方便等优点。通过与理论解的比较，精度是令人满意的。
Numerical simulation of the flow of highly viscoelastic flow in three-dimensional slit channels has been carried out by half-numerical analytics method (HNAM) which was developsed in this paper according to the lubricenting approximation theory. HNAM can changes threedimensional problem to two-dimensional one. It is proved through a comparison with analytics solution that HNAM possesses higher accuracy and only needs less space and CPU in computation.
