制衣车间湿帘降温系统的CFD模拟

为研究湿帘降温系统在热湿地区制衣车间的热环境分布情况，使用计算流体动力学（computational fluid dynamics，CFD）方法，模拟湿帘降温系统下制衣车间内部温度场与相对湿度场的分布。用现场测试结果及计算结果设置相应边界条件,模拟结果显示，沿湿帘进口到负压风机出口方向室内温度呈递增趋势，平均每米增加0.031 ℃，室内相对湿度呈递减趋势，平均每米下降0.37%。将温度值和相对湿度值的模拟结果与测试结果进行对比分析，可知温度平均误差为0.57%，湿度平均误差为4.9%。研究证明了所建立三维CFD模型的准确性，为湿帘系统在制衣车间的布局优化提供参考。

CFD Simulation of Wet Curtain Cooling System in Garment Workshop

That hot weather conditions cause wet curtain cooling system for garment workshop indoor temperature and humidity regulation is not obvious in southeast China.Computational fluid dynamics，CFD was used to calculate temperature and humidity distribution of wet curtain cooling system.The results was field test and computation were employed to set the corresponding boundary conditions.The simulation results showed that the increment rate of temperature of the wet curtain along with negative pressure fans direction was about 0.031 ℃per meter in correspondence with the decrement rate of relative humidity about 0.37% per meter.It the results from simulation and experiments for temperature and relative humidity is respectively about 0.57% and 4.9%，which verifies the accuracy of the establish three-dimensional CFD model.It can be conclude that the result from the set model is beneficial to the layout of the clothing workshop.
