数值计算方法在《传热学》课程教学中的应用

Application of Numerical Calculation Method in the Teaching of "Heat Transfer"

为加深学生对《传热学》课程中热传导的数值解法以及对流传热知识的理解,本文选取二维平板导热问题以及典型对流传热问题的数值计算案例,采用Excel软件迭代计算以及CFD仿真软件的模拟分析,并结合多媒体技术进行现场操作和演示,在提高学生学习积极性的同时,帮助学生理解数值计算方法在复杂传热问题中的应用以及不同类型对流传热问题的特点和演变规律。

To make students better understand the contents of numerical method for heat conduction and convective "Heat Transfer" in the course of heat transfer,this paper introduced the cases that use the Excel software and the CFD approach to simulate the problems of heat conduction in a 2D plate and convective heat transfer,respectively.The simulation results are shown with the help of multimedia technology to help students better understand the numerical simulation technique and the mechanisms of different types of heat transfer,and meanwhile increase the interest of students in learning.
