有限差分法求解一维不稳定态变物性热传导问题

One-Dimensional Unsteady Heat Conduction Question of Variable Physical Properties With Finite Differential Method

应用有限差分法，选用控制容积积分法推导出离散化方程组，对一维不稳定态变物性热传导问题进行求解，计算出钢包在预热过程中包衬的温度分布．在计算程序中编有温度分布曲线描绘程序，在输出各点温度值的同时打印出温度分布曲线，使计算结果直观、明了．

With finite differential method, the discretization equations are derived by chosing control volume integral method to solve the unsteady one-dimensional heat conduction question with variable physical properties, and the temperature distributinn in ladle lining in preheat is computed. the subprogram for the drawing of temperature distributation curves is written in the computation program, and the temperature distribution curves are printed when temperature at every point is given, which makes the results audio-visual and clear.
