The New Solution for the Axially Symmetrical Laminar Boundary Layer Equations between Two Parallelf Spherical Surfaces

摘要: 本文给出了与Mangler变换类似的变换,它将平行球面间进口段内层流轴对称边界层流动转换成二维平面层流边界层流动,使问题得到简化.简化后的方程可以用已有的平面层流边界层理论和数值方法来求解,从而为求解平行球面间扩散层流进口段问题提供了一条新的途径.

Abstract: The transformations,which are similar to Mangler's transformations,are given in this paper.They change the entrance region flow of axially symmetrical laminar boundary layer between two parallel spherical surfaces into the flow of two-dimensional boundary layer,and simplify the problems.The simplified equations can be solved by the two-dimensional boundary layer theory and numerical methods.Therefore,a new way is opened up to solve the diffusive laminar flow in the entrance region between two parallel spherical surfaces.
