| 摘 要： | 为了解温室内部温度场的动态变化过程,优化传统的通风控制系统。对机械通风下的连栋薄膜温室的温度场的动态变化进行了试验,并根据试验温室的几何结构和试验数据,使用CFD方法对试验温室进行数值建模,在模型中考虑了太阳辐射和热辐射,应用FLU-ENT软件进行模拟计算。通过在试验温室采集到的关键位置的温度数据,与模拟结果比较发现CFD数值模拟的室内温度变化的趋势与试验测试的结果基本一致。

| Abstract: | In order to get to know dynamic process of temperature field in greenhouse, optimize traditional air control system, the experiment was conducted on the dynamic change of temperature field of multi-span plastic greenhouse under mechanical ventilation. According to the geometric structure of the greenhouse and test data, CFD method was used to conduct numerical modeling. Considering the solar radiation and heat radiation, FLUENT software was adopted to conduct simulation calculation. Compared with simulation results, greenhouse temperature variation trend simulated by CFD is accordance with testing results. |
