玻璃基板的品質好壞可以由最終產品中介在物以及殘留氣泡的多寡決定，而玻璃熔解窯爐批料進入混合以及澄清攪拌之過程均勻與否，與殘存物質去除有密切的關係，因此如何能有效提升混成時間與減少滯留區是一項重要的課題。由於真實窯爐內之資訊及流場取得不易，而全尺寸模型之研究有其困難之處。因此本研究建構一實際窯爐十分之一的壓克力模型，其相關裝置設備皆仿照原始窯爐操作。利用高黏度的矽油取代熔融玻璃，並以高分子追蹤粒子進行物理實驗的量測與觀察，日後可驗證數學模擬。

本研究分別探討三種加熱溫度與有無底吹氣體（流量40cc/min）等不同的操作條件，結果發現加熱條件改變與底吹氣體會帶動不同的區域攪拌環流並且影響其流動軌跡，能有效提升滯留時間，減少停滯區的範圍，以助生產高品質的玻璃基板。本研究綜合幾種評估指標後並找出較適合操作條件以提供數模模式分析、窯爐工作者參考依據。

The quality of the glass substrate depends on the number of the bubble and the impurities in the final products, but whether the process of bath enters and clarifies in the glass melting furnace homogeneous or not relate to the elimination of residue, so how to improve the mixing time effectively and reduce the residence area is important . Because it is difficult to received the information and flows field in the true furnace and the research of the full-scale model is really difficult. This research builds an acrylic model which scale is 1/10 of real one, and its equipment relevantly imitates the primitive furnace. Utilize silicon oil of high viscosity to replace melting glass and high polymer tracers to measure and observe the physical experiment, furthermore ,expect to verify the
numerical model in the future.

This research confer three kinds of heating temperature separately and with or without bubbler (40cc/min).The result indicate that the heating condition and bubbler can effect circulation area and increase the resident time, besides, decrease the dead zone and improve the quality of
glass substrate. This research combines some estimate index and find out relatively appropriate condition consulted to numerical model and furnace worker.
