Abstract

In this paper, we simulated the Huabei-type multispan plastic greenhouse of Beijing with software of CFD (Computational Fluid Dynamics). Here the greenhouse is provided with mechanical ventilation, cooling pad and without plant in it. We successfully simulated the velocity and temperature distribution in Huabei-type multispan plastic greenhouse with different cooling pad height and its fixing height. The compute value tallied the experiment value. It is useful and important for more understanding the internal climate of the greenhouse, optimizing the design of ventilation facility and improving greenhouse control systems.
