摘　　要：采用计算流体力学软件GAMBIT对安装有湿帘风机系统的三连栋温室进行三维几何建模,然后采用FLUENT软件对温室在夏季典型的气候条件下的内部温度场进行模拟计算,通过稳态计算得到了温室内部温度场的分布图。并依次分析了在几种风机通风风速、太阳辐射强度时,温室内温度场表现的温度分布特征。A three-dimensional model of multi-span greenhouse ventilated with fan and pad cooling system was built by GAMBIT,and its temperature field under typical summer climate condition was simulated by using computational fluid dynamics software FLUENT,the distribution was obtained through steady calculation.The temperature field distribution under different circumstances such as different ventilations,different solar radiations were illustrated.
