摘要(中)

近年來人們開始利用屋頂裝設風機與太陽能板來獲得再生能源。本篇研究使用風洞實驗探討太陽能板在平屋頂的建築物上的風力負載。在兩種不同的入流下，分別量測了建築物在不同風向角下，屋頂上方的速度流場與壓力分佈。結果顯示屋頂上方最大紊流強度發生於高度z/Hb = 1.1至1.2處。鑒於前人對於在屋頂上太陽能板的研究，本篇論文透過風洞實驗改變建築物風向角、女兒牆高度及太陽能板座向角來研究平頂建築物上方太陽能板的風力負載。實驗結果顯示：當風向角為0o時，屋頂最大負壓發生於建築物屋頂前緣，而女兒牆可減低建築物屋頂前緣的負壓力約15 ~ 25%。當風向角為45o，女兒牆可減低建築物屋頂角隅的負壓力約20 ~ 25%。當屋頂無女兒牆的狀況下，風向角為0o及45o時，太陽能板所受的升力向下，風向角為180o及225o時，太陽能板所受的升力向上。不論風向為何，太陽能板的高度愈高，其所受的淨風壓係數的絕對值愈大。當屋頂裝設女兒牆後，太陽能板所受的淨風壓係數皆大幅減小。

摘要(英)

Nowadays people started to install wind turbine and solar panel to gain renewable energy. This study used wind tunnel to investigate the aerodynamic loading on the solar panel installed on flat building roofs. The turbulent velocity and pressure distribution on the building roof were measured in two different approaching flows. The maximum turbulence intensity occurred at height z/Hb = 1.1 to 1.2. This study also investigated the influences of wind direction, parapet height on the aerodynamic loading of the solar panel. The flow conditions include three different panel heights, two panel orientations and four wind directions. For the pressure on the building roof, the maximum negative pressure occurred at the leading edge when wind direction  = 0o. The roof parapet, due to the shelter effect, can reduce the time-averaged corner pressure 15 ~ 25%. For wind direction  = 45o, the parapet can reduce the pressure 20 ~ 25%. For the aerodynamic loading of the solar panel on building without parapet, the net pressure on the solar panel increases as the panel height increases. The worst case (maximum aerodynamic loading) occurred when the wind direction is 225o and the orientation of the panel with the building is 45o (wind is normal to the lower side of the panel). For solar panel with the parapet, the net pressure coefficient of the solar panel is smaller than that of without the parapet.
