The new solutions for two kinds of axially symmetrical laminar boundary layer equations. (English) Zbl 0728.76036

Summary: The transformations, which are similar to Mangler’s transformation, are given in this paper, and make the two kinds of entrance region flow of axially symmetrical laminar boundary layer in internal way into the flow of two-dimensional boundary layer, and simplify the problems. The simplified equation can be solved by the 2-D boundary layer theory. Therefore, a new way is opened up to solve the axially symmetrical flow in the entrance region of internal way.
