两种椭圆型方程求源项方法在喷管内流场网格生成中的应用

TWO METHODS OF EVALUATING SOURCE TERMS OF ELLIPTIC SYSTEM IN THE GRID GENERATION OF NOZZLE INTERIOR FIELD

用椭圆型方程生成二维网格，发展两种Hilgenstock求源项方法，实现对网格与边界间距及与边界正交的控制。

Two Hilgenstock metheds are developed for evaluating source terms of elliptic systemin 2-d grid generation. The angle and spacing of grid lines to boundaries can be adjusted to specifiedvalues.
