对二维导热问题进行了离散化研究,推导出了节点差分方程,以矩形薄片为例,用MS.Excel对节点温度进行了计算,用MATLAB对计算结果进行了仿真,得到了薄片的温度分布仿真图.
The discretization of two- dimensional heat conduction was studied and the nodal point difference equation was deduced. A rectangular- shaped thin slice was taken as the example to carry on the computation with MS. Excel to the nodal point temperature. The simulation was carried on with MATLAB. A simulation chart o of temperature distribution of the thin slice was obtained.
