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.
