Abstract

A three-dimension temperature distribution image of a forced ventilated greenhouse is given by calculating steady-state temperature fields based on a computational fluid dynamics modeling of a multi-span greenhouse from CFD software FLUENT. A experiment of measuring temperatures in several specific position inside the greenhouse and other climate parameters outside is conducted in a real production greenhouse, and a comparison is done to verify the accuracy of CFD model of the presented greenhouse. The results show that if more boundary conditions are defined with the measured value a more accurate model can be expected and some excellent prediction of temperature can be achieved.
