摘要:
用基元有限容积方法,在非结构化网格中离散和求解热传导方程,二阶迎风格式和全程隐式迭代求解稳态导热问题.在验证求解方法的算例中,结构化和非结构化网格同时采用,并且提供了3种非结构化网格(三角形网格、四边形网格和混合网格)的计算结果,同时用精确解与得到的数值解相比较.虽然两种网格形式都能得到满意的精确度结果,但对于非正交的非结构化网格,二次扩散项对提高精度是十分重要的.
Abstract:
Conduction heat transfe r prob lem s are so lved w ith a cell- based finite vo lume m ethod ( FVM ). The second upw ind schem e and w ho le processing im plic it iteration way a re used. The so lutions are ob tained by using structured g rids and unstruc tured grids tha t inc lude three kinds o fm eshes ( triangu lar, quadrila tera l and hybrid). Som e results are com pared w ith the exact solutions. A lthough both structured and unstructured m eshes produce accura te so lutions, structured gr id so lutions a re mo re accurate than the triangu lar unstructured gr id and are the sam e accurate as sim ilar quadrila teral unstructured gr id in rectangular reg ion.
