在对称域或非对称域中,用结构化或非结构化网格中有限容积方法对稳态热传导问题进行数值求解.同时,采用伽略金近似方法分别对不同形状域求其近似解,并与精确解或数值解进行比较分析.在此基础上对几种计算方法所得结果进行误差分析,通过比较计算结果可以得到令人满意的一致性.这些都充分证明伽略金近似方法和本文给出的数值方法的可靠性和实用性.%On bounded symmetry and asymmetry domains,the steady state heat conduction equations were solved and calculated by using the finite volume method in structured or unstructured meshes.Also,the approximate solutions of different domains were derived on the basis of the concept of Galerkin method.Compared with these calculation results,there is a good agreement between them.These proved that Galerkin approximating method and numerical calculation are believable and practical.
