摘要
基于热渗透层厚度概念的积分法是求解非稳态传热问题的一种有效的近似分析解法 ,既保留了经典理论解具有统一数学表达式的优点 ,也兼顾了数值解法较为简单快速的特点 .
The integral method based on the concept of thermal boundary layer is a valid approximate analytical method for solving the unsteady heat transfer. It maintains the advantage of the classic analytical solution with unified mathematic expression and has the characteristic of numerical method with rapidly computing. In this paper , the approximate analytical solution of unsteady heat transfer in large plate under the first boundary condition has been derived from this method.
