本研究採用理論分析及風洞模型實驗的方式來研究有室內隔間之建築物風壓通風的問題，研究參數包括室內隔間的方式、室內開口的大小、厚度對通風量的影響，通風量和開口的流量係數利用噴嘴流量計來量測。實驗結果發現室內開口的流量係數與損失係數為開口大小的函數，但與雷諾數、內外牆厚度、室外開口大小與位置無關。研究也發現了當迎風面與背風面面積相同時，通風量會最大，
且此通風量會隨室內開口變大而變大。本研究並依據連續方程式和孔口流量公式建立一個預測模式來計算多區間建築物(Multi-room)的風壓通風之通風量，風洞實驗的結果驗證了此預測模式，此模式可供建築設計者未來在評估、規劃建築物自然通風之用。

| dc.description.abstract | Abstract
This study uses wind tunnel experiments to investigate wind-driven cross ventilation in partitioned buildings. The discharge coefficients of internal opening were determined by a fan technique. It is found that the discharge coefficient is a function of internal porosity and door angle, but independent of Reynolds number, opening thickness, external porosity and opening location. This study also discovered that the internal discharge coefficient decreases as the internal opening area increases. However, the ventilation rate increases as the internal opening area increases. Based on the experimental results, a predictive model for inlet velocity and internal pressure of multi-room buildings was developed and verified. This model can provide architects to evaluate the ventilation rate and thermal comfort of nature ventilated buildings.
