摘要
对第三类边界条件中所使用的对流换热系数应用于非稳态导热过程存在的问题从理论上进行探讨 ,通过计算分析表明 。
Newton's Law of cooling in many situations is taken as boundary conditions of unsteady conduction,in these cases parameter α (heat transfer coefficient) is usually treated as a constant.The analysis and computation in this paper shows that treating α as constant will bring big error to the solution to unsteady conduction.
