摘要
介绍了求解导热问题的一般方法,提出了点热源和线热源两种物理模型,并使用MATLAB对其进行数值求解,分析了不同加热功率、不同网格划分对温度场的影响;分析了数值计算引起的误差原因及其所提及的两种物理模型的工程应用价值。
General methods in solving heat transfer problem are introduced, two physical models: point and wire hot source are mentioned and using MATLAB to solve the two models by numerical methods, the different heat up power and mesh's influence on temperature field are analyzed. At last, reasons which will bring numerical calculation error are indicated, engineering importance about the two physical models are presented.
