    Abstract: 本研究是探討計算流體力學(CFD)軟體應用於人工智慧專家系統中,並利用數值模擬所分析出來的資料製做成資料庫,將CFD軟體設定成可以用專家系統來操作。藉由FDS軟體模擬風場案例來了解建築物受風後環境風場的情況,探討出適合的參數設定,以便設定於專家系統,可以預測實場情況,並且藉由模擬出來的防風設施效果來建立資料庫,給予適當的建議與改善方法。
      研究方法主要分成兩部分,第一部分假設風場環境案例兩棟建築物來做設計探討;使用 FDS 模擬規劃出須輸入的資訊,以及控制模擬所需的時間;模擬結果再與日本風洞試驗數據做比較。並將參數設定歸納出如何使用於專家系統中。
    This study was to explore the CFD software used in artificial intelligence expert system, and analyzed using numerical simulation of the system made of the information database, the CFD software can be set to operate with the expert system. By FDS simulation software to understand the case of wind farm buildings by the wind after the wind environment case, of the appropriate parameter settings and expert systems, and predict real market conditions, and out of the wind facility by simulating the effect to create a database, with appropriate advice and ways of improvement.

      A research method is to simulate a hypothetical case of two buildings to the design wind environment. FDS simulation program using the input information, and control the time required for simulation. Japan''s wind tunnel simulation results with experimental data and then compare. And how to use the parameter settings summarized in the expert system.

      Wind facilities are based on numerical simulation methods to compare with the experimental value, simulations using Fluent in planting set the porosity compared with the results of the experimental data. Canopy simulation using six types to be compared with the experimental data. The results showed that planting of wind effects can reduce wind speed of about 30 to 50%, while the poncho is better on both sides, the wind speed can slow about 18%.
