摘　　要：圆管道内充分发展的层流和传热是热传导方程应用中一个有趣而重要的分支.本文给出几种在不同流道几何形状和热边界条件下,用非结构化网格方法进行数值计算的结果,并与结构化网格的计算结果进行比较分析,从而证明本方法和所给程序的正确性和实用性.The fully developed laminar flow and heat transfer in duets are an interesting and important research field of the heat conduction equation. In this paper, the veloeity and energy governing equations that are similar to the heat conduction equation are solved by using the unstructured grids in several duet geometries and thermal boundary conditions. Mean- while, the solutions are analyzed and compared with the results by using structured grids, thus the method and procedures are justified.
