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 the two-dimensional heat conduction problem is studied, and the node difference equation is deduced. Taking the rectangle slice as an example, the node temperature is calculated by using MS.Excel. The calculation results are simulated by MATLAB and the temperature distribution of the slice is obtained Simulation chart.
