作物高度对温室自然通风影响的CFD分析
CFD Analysis about Effect of Plant Height on Natural Ventilation in Greenhouse
摘要
Abstract
In recent years, with the improvement of computer performance and technology,computational fluid dynamics method has been widely used in facility agriculture.The paper study the distribution of air flow and temperature under dif-ferent height of crop in a naturally ventilated Venlo greenhouse with computational fluid dynamics method.The results for the natural ventilation show the significant effects of different crop height on air flow velocity in greenhouse.The air veloc-ity at the height of 1.2m in the greenhouse is less than 0.2m/s while the outdoor wind speed at 1.5m/s.Crop height had a greater influence on the temperature variation along the span direction in the greenhouse.The higher crop height grows, the more obvious temperature change.The average temperature at the level of 1.2 m was obtained by the simulation, the influence rule was obtained in crop height for the temperature on the natural ventilation.关键词
