    • 本篇研究使用風洞實驗以及數值模式探討平頂建築物上太陽能追蹤器的風力負載。鑒於前人對於在屋頂上太陽能追蹤器的研究，本篇論文透過風洞模型實驗在不同的風向角、建築物與太陽能追蹤器之間的座向角、高度及傾斜角狀況下，量測太陽能板上下表面的風壓分佈以計算其所受風力與彎矩。

    This study used wind tunnel experiment and numerical simulation to investigate the aerodynamic loading on the solar tracker installed on flat building roofs. The surface pressures on the model tracker were measured under different wind directions, azimuth angles, inclined angles and pedestal height of the tracker.
