| Abstract: | 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. |
