摘　　要：顶部可完全打开的塑料温室能更好地满足采光、降温、换气、除湿的要求,为作物的生长提供更适宜的条件。介绍一种顶部可“折扇状”收放的塑料温室为研究对象,应用CFD数值方法对其封闭状态的风压及风速等进行模拟。通过对不同风向来风时的流场分析,得出温室表面风载的特征及其分布规律,说明CFD方法在风压分析方面的有效性,分析结果可以为温室的结构设计以及建造提供有价值的参考。The plastic greenhouse that can be fully opened at the top can better meet the requirements of lighting,cooling,ventilation and dehumidification,and provide more suitable conditions for the growth of crops.In this paper,the wind pressure and wind speed of a kind of plastic greenhouse with"folding fan"top as research objects are simulated by CFD numerical method.Through the analysis of the flow field when the wind comes from different wind directions,the characteristics and distribution rules of the wind load on the surface of the greenhouse are obtained,which shows the effectiveness of the CFD method in the wind pressure analysis.The analysis results can provide valuable reference for the structural design and construction of the greenhouse.
