    摘要: 都市地區由於高樓林立，地表附近之流場明顯受到周圍建築物之影響而產生較大的風速擾動。進幾年因電腦運算速度的提升以及軟體所提供的模式能有效地提高數值模擬的準確性；數值模擬可以有效地降低實驗量測所需要花費的時間與實驗成本的支出。本研究即以台灣85大樓新建纜車路線方案為一個案例，對於纜車沿線流場之特性進行分析比較。該大樓樓高347m，纜車位置離地約130m，該處建築物寬度約120m，深約50m。風洞試驗：風洞試驗縮尺為1/350，並以熱膜風速探針量測風速與紊流強度。數值模擬：利用Gambit2.3建立主建築物與周邊建築幾何形狀、網格繪製、邊界條件的設定，最後使用FLUENT6.1.2進行數值模擬的分析與結果輸出。風洞試驗與數值模擬分析相互比較的結果發現：流場的趨勢與平均風速值是相當一致的。
    Due to the large among of tall buildings in the city, it is very obvious that stream line which nearby the surface of the earth is affected by the surrounding buildings and resulting in large disturbance of wind velocity. Recently, the new computers are more powerful and the software could be developed different models to advance the accuracy of computational fluid simulation effectively. Computational fluid dynamics can decrease time and defrayment of experiment cost effectively for the experiment measurement. This study will take new cable-car route of Taiwan 85 building as a case comparing with the characteristic of stream line. The height of the building is 347 m. The station of cable-car is located at evaluation of 130 m. The station width and depth are 120 m and 50 m respectively. The similarity is 1/350 and used hot film to measure wind velocity and turbulent intensity in the wind tunnel. Using the software of Gambit2.3 to build the different height of buildings, mesh grids and set boundary conditions. Finally, using the software of FLUENT6.1.2 to simulate and result of data to output and plot. The stream field and mean velocity in the wind tunnel measurements are good agreements with computational fluid dynamics results.
