集合住宅中庭植栽微氣候之數值模擬研究

Numerical Simulations on the Urban Microclimate Influenced by the Plants in the Open Space of a Condominium

摘要


本研究以計算流體力學(Computation Fluid Dynamic, CFD)模擬軟體與現場實測資料交互比對,探討植栽模型的參數設定方式與有無植栽對於流場的影響。研究結果顯示,就高層集合住宅的室外中庭而言,植栽孔隙介質的設定以動量方程式中加入植栽的流場特性的結果與實測值較爲接近;另外在有無植栽模型群組的模擬結果中,2m高處的風速比爲10.7(有植栽風速值/無植栽風速值),顯示有植栽模型對氣流有導引效果,促使「近地面層(人體活動範圍)」之風速增加。

並列摘要


In this study, CFD (Computation Fluid Dynamic) simulation software and actual measurement are used to investigate the relationships between plants and the wind field in the open space of a condominium. The better simulation values of the porous plants media test is the momentum equation combines with wind field characteristic of plants. In addition, the comparison between plants model and without plants model, the wind speed ratio at 2m above the ground is 10.7, which is the wind speed with plants divided by the wind speed without plants, it shows that the plants of a condominium can lead airflow toward the pedestrian level, and increase the wind speed to advance human comfort.
