| 摘 要： | 用基元有限容积方法求解热传导问题,结构化网格和非结构化网格同时采用,并和精确解相比较.虽然从两种网格形式,都能得到满意的结果,但结构化网格在规则区域更精确一些.对于非结构化网格,二次扩散项对提高精度是十分重要的.

| Abstract: | Conduction heat transfer problems were solved using a cell-based finite volume method. Solutions were ob-tained using structured and unstructured grids. All of the results were compared with exact solutions. Although both structured and unstructured grids produce accurate solutions, the solutions of structured grids are more accurate than the solutions of triangular unstructured grids in rectangular region. |
