本計畫預備採用理論分析及風洞模型實驗的方式來研究風壓通風的問題,研究參數包括風速、風向角、通風開口的大小、形狀(正方形、圓形、長條形)、形式(有紗網、百葉窗、水平導風板、垂直導風板等裝置)和室外風場(包括無紊流、紊流和陣風風場)對通風量的影響,通風量和流量係數將會以高精密度的方式來量測。量測數據分析整理之後,將建立一個不需利用計算流體動力學(CFD) 的簡易模式來計算建築物的通風量,期望此模式可提供建築設計者未來在規劃建築物自然通風之參考依據,並期望能改善台灣本土室內空氣品質與通風環境,達到綠建築節能、健康的理念。 ; This research project proposes to use theoretical and experimental approaches to study cross ventilation of buildings. We plan to study the influences of wind speed, attack angle, size and shape of opening and outdoor flow conditions (laminar flow, turbulent flow and gusty flow) on cross-ventilation in a large scale wind tunnel. The ventilation rate and discharge coefficient will be measured with high accuracy methods. The results will be analyzed and used to develop a simplified model, without using Computational Fluid Dynamics (CFD) models, to calculate ventilation rate of buildings. This model can provide the architects to evaluate the ventilation rate of buildings. ; 研究期間 9708 ~ 9807
