A support system for natural ventilation design of greenhouses has been developed, based on computational aerodynamics. This system can predict the distribution of air flow, temperature, humidity, and gas concentration under various conditions of greenhouse structures including the configurations and arrangements of ventilator openings, plants, and meteorological conditions. The predicted distributions of environmental factors are presented user-friendly in graphic displays. The current results demonstrate that three-dimensional numerical simulation, which includes the k-epsilon two equation model to simulate turbulent effects, can be applied to the qualitative prediction of air distribution in a naturally ventilated greenhouse as a powerful tool for design.
