第五章 縮尺鹽水模型實驗
5.5 未來展望
目前的實驗，是以單一空間為模型，在未來的實驗中，必需再研究更多 不同的模型，例如有隔間的，有走廊的，有出風口，有門的等，以符合實 際居住環境或活動空間的環境，讓縮尺實驗更能對應全尺實驗的結果，更 發揮縮尺實驗經濟效益高，結果也能相符合的特性。

第六章 結論與未來展望
此第一期計畫的結案報告就火載量、火柱模式、能量及室溫、煙的產 生及煙控、撒水作用之質、熱傳及簡易之桌上型縮尺鹽水模型之建構等項 目進行探討，除獲得單一模式建立的初步結果外，實驗的架構及實驗數據 的整理法則等亦已具雛形。未來若能持續進行理論及實驗工作，將可獲得 更具意義的分析結果及實驗數據，俾能提升預估火災現象及其中各項因子 交互影響作用等二方面的能力。
計畫可能遇到的狀況與未來的展望列述如下:
1. 為避免所模擬火災事件與可能發生情況不符，排煙及撒水設備 與現今建管、消防所要求者有所出入，將視需要諮詢相關人員。
2. 將持續搜集有關資料，使模式的建立更具彈性，考慮的因素更 多，適用的範圍更大。
3. 第三期(為時一年)的計畫將進行大尺度煙流的實驗量測，於第二 期內將預作規畫，估算經費，並與主管當位溝通，期能於第三 期時能使用建研所或相關單位現已有的實驗場所及設備進行實 驗，若有需要，當添購設備或調整實驗場所，使實驗所得值更 能切合實際所需。

火災排煙設備與自動撒水系統交互影響之研究案會議記錄
一、 時間：民國八十九年六月二日（星期五）上午九時三十分 二、 地點：中原大學機械系會議室工205 室
三、 主持人：鄧教授治東 四、 出席人員：
警察大學：簡教授賢文；建研所：蘇博士文瑜；消防署：陳專門委員文龍、
馮科長俊益。
五、 會議記錄：
（一） 本會議內容主要包括兩大部分：撒水液滴於火災環境中質量與熱傳變 化之討論，以及桌上型縮尺鹽水模型實驗之觀摩。
（二） 對於撒水啟動之後，通風口是否會因為水與熱、煙之交互作用而無法 動作，仍需要加以討論。
（三） 目前設計之空間較小，為了符合真實狀況，希望將來能延伸至使用於 大空間之狀態。
（四） 關於撒水後室內的熱傳現象，仍須加以考量。
（五） 在撒水實驗中，由於顏料出口的速度較快，所以剛開始應為 laminar flow ，建議宜考量改善方法，例如：出口改用 nozzle 等方式。然而，
於鹽水實驗時，因為出口的速度較大，所以可將之視為成長期，應屬 於 laminar flow 。同時，正因為速度快，較快達到 turbulent flow ， 若用 nozzle 的話，出口的面積較大，速度會相對變小，可能達到 turbulent flow 所需的時間會變長，所以還需在進行實驗後才能確定。
