摘要
通过介绍工业生产中一冷却平台的结构和工作环境,建立模型,对该模型进行了初边条件的设定和网格的划分,并在三维适体坐标下对非稳态无内热源导热方程离散。应用在不同尺寸模型下的数值计算,得到冷却平台的温度场和符合生产要求的非稳态导热时间,并对结果进行了分析和论证。
Through the introduction of a cooling platform structure and working environment in industrial production, its mod- els is established, the initial boundary conditions and the grid are divided for the models, and unsteady state conduction equa- tion without inner heat is discreted in three dimensional body fitted coordinates. Numerical calculation in different size models, the platform cooling temperature field is got and the production requirements could meet the unsteady state heat conduction time, and the results are analyzed and demonstrated.
