摘要
针对西安市某印刷车间生产运行时对风速的特殊要求,为确定较优送风速度,借助FLUENT前处理软件Gambit绘制模型,完成网格划分,设置初始边界条件,对不同风速工况时,即出风口速度分别为5.0和5.5 m/s时,印刷车间室内不同水平面及垂直面的温度场和速度场分布规律进行模拟分析,得出风速为5 m/s的工况下,风速分布均匀性指标较优,温度分布有利于车间内污染物的排出。研究结果可为印刷车间正常运行提供良好的室内空气环境。
According to the special requirements on wind speed of the production and operation of a printing workshop in Xi＇an,in order to determine the optimal supply air velocity,the paper took advantage of FLUENT to simulate the wind speed and temperature distribution of different horizontal and vertical surface in the printing workshop under different wind speed conditions,in particular,the outlet wind speeds were set by 5.0 and 5.5 m / s respectively.But rendered model and completed mesh and set the initial boundary conditions by the Gambit software before using Fluent.It shows that when the wind speed is 5.0 m / s,wind speed distribution uniformity index is better and the temperature distribution is conducive to the discharge of pollutants in the workshop.This study can provide a good indoor air environment for normal operation of printing workshop.
