| 摘 要： | 应用计算流体力学建立了华东型连栋塑料温室的二维、稳态的湍流模型,对普通齿条开窗和法国式大开窗两种常见的顶窗开启方式的温室,特别是作物层的自然通风速度做了分析比较。结果表明,普通齿条开窗的温室到达出口的通风速度略大于法国式大开窗的温室,但后者通风的均匀性明显好于前者。

| Abstract: | A steady turbulence model was studied using two-dimensional computational fluid dynamics (CFD). The analysis of the ventilation process in greenhouse, especially in crop field was performed by comparing the normal flap windows and France-type flap windows. As to the ventilation velocity, the value of the outlet is greater in the greenhouse with normal flap windows than in that with France-type flap windows. But the equality of the ventilation is better in the latter. |
