Abstract: 
本研究以計算流體力學來分析台荷溫室結構在外部風場驅動下內部流場的特性,在狹長的四行Venlo-type溫室架構下,不考慮邊緣效應而以二維剖面的方式來作分析。假設外部風場速率為0.5 m/s,在溫室內部空無一物的情況下,分析了天窗及側捲揚在不同開啟姿態下的內部流場狀況。天窗及側捲揚的適當配置,可抑制流入空氣尋最短路徑的趨勢,有效提高溫室內空氣的換氣流動。此外放置擾流板於適當位置可有效消除附壁效應,避免流入空氣從後鄰天窗直接流出,而目前的溫室設計架構只有迎風面第一扇天窗可擷取外部風場。
This study analyze the internal flow properties of four-span Venlo-type greenhouse under 0.5 m/s wind blow with the 2D profile computational fluid dynamics technique, where the end effect of greenhouse is neglected. On the condition of empty greenhouse, the effects of different top and side windows configuration on internal flow are analyzed, and the best setup for enhanced internal air exchange is found. Only the first top-window facing wind blow can take air indoor under the current design. Besides, the properly-situated baffle plates can eliminate the Coanda effect, and guide air flow deeper.
