A finite difference method of calculating boundary layers of axisymmetric nozzles
Abstract
In this paper a finite difference method for calculating an axisymmetric wall boundary layer is suggested. An implicit scheme with parameter omega is used. When omega is equal to 1/2, the scheme is equivalent to Cabeci and Smith's method. But if omega is greater then 1/2 the scheme will more stable as known. Computation shows that when omega is equal to 0.75 this scheme can stably calculate flows near separation. Five examples are given and compared with theoretical solutions or experiment data.
