摘要

本研究利用電腦模擬技術，分析TFT-LCD平板玻璃溢流熔融製程(Over-flow fusion process)中，成型機構的幾何外型與液體流量及黏度對於平板玻璃成形的影響。同時並建立一組類比實驗來與電腦模擬結果相比對。在模擬技術方面，將採用Flow3D(上標 TM)套裝軟體，藕合流體力學方程式、自由表面及接觸角處理技術，來模擬玻璃膏在溢流槽的流動及溢流情形。由模擬的結果發現，溢流槽的幾何形狀及玻璃膏的流量與黏度控制對平板玻璃的成形有很大的影響。

The computational modelling of the over-flow fusion process, manufacturing a flat glass for the use of TFT-LCD, was carried out. The flow rate and the viscosity of molten glass flow, influencing the formation of a flat glass, as they encounter to the geometry of an apparatus, was studied. Using an analogy method, a physical experiment of molten glass flow was conducted. The result of computational modelling was validated by the experiment. In modelling, a general CFD code (Flow3D(superscript TM) was used. In the numerical model, the continuity and momentum equations were incorporated with the free surface transport equation. In the result of modelling the overflow process, the thickness of the formation of a sheet glass was influenced by the geometry of overflow trough, and the flow rate and viscosity of molten glass flow.
