摘要:: 热量传输现象在工程技术领域中广泛存在，对二维稳态传热情形下温度场分布的研究有重要现实意义。对于复杂几何形状的物体和非线性的边界条件，分析解法显得无能为力；相比之下，建立在有限元基础上的数值计算是有效和准确的。在传热和流体流动问题的数值计算方面，SIMPLE算法被广泛采用。通过VC和Matlab的混合编程用SIMPLE算法实现了对二维稳态传热问题的计算仿真，描述了温度场的分布

Abstract:: Because heat transfer phenomena are widespread in the field of engineering technology, the researches on two - dimensional steady- state heat- transfer temperature field distribution have important practical significance. For objects with complex geometry and nonlinear boundary conditions,the analysis method is powerless; In eontrast,the numerical calculation based on the finite element is valid and accurate. The SIMPLE algorithm is widely used in the numerical calculation of heat transfer and fluid flow problems. The mixed programming with Visual C ＋＋ and Matlab through SIMPLE algorithm make a computerized simulation for the two- dimensional steadystate heat - transfer problem, and the temperature field distribution is described in detail
