    摘要: 本篇文章中配合實驗儲存槽整體結構,利用GAMBIT繪製與實驗相同的幾何結構,再使用FLUENT設定邊界條件、液體性質等設定,並讀取運算出的數據與溫度分層圖。
    儲存槽體積為61.6L,槽內放置熱管與冷管的熱交換器,分別將340K熱水,流率為0.471 l/min通入熱管中,另外將300K冷水,流率為0.094 l/min通入冷管。實驗數據與使用FLUENT模擬後的數據作比較,確定模擬的設定能夠符合實驗後,改變冷熱水進口溫度、冷熱水進口流率、盤管與槽內液體的接觸面積、流體種類等各種方式,對儲存槽內溫度分層狀況以及冷水出口影響。
    The study reveals that good agreement between simulation and experimental results was achieved. GAMBIT can plan the same geometry structure with experimental, and use FLUENT to establish boundary condition, liquid properties. We read the data and the temperature contours from Fluent.
    The heat exchanger flow rate and surface area are important factors to increase the performance of solar thermal systems. The paper deals with flow rate and surface area in closed loop flat plate solar collector systems. The system employs a flat-plate collector with a surface area of 3.6 m2 to drive a storage thermal tank (61.6 L). The heat and cold pipe heat exchangers in the storage tank. The rate of discharge is 0.471 l/min passes over in the heat pipe, and the rate of discharge is 0.094 l/min passes over the cold tube. The performance of this system is presented and compared with simulated results.
