摘要:

 使用FLUENT软件,采用压力修正法和流体体积法对溢流砖表面玻璃液的分布状态进行三维数值模拟。研究了溢流砖长度、溢流砖上表面倾斜角度、入口压力、玻璃液黏度对溢流砖表面玻璃液分布均匀性的影响。结果表明,在高世代大尺寸的溢流砖设计中,需在加长溢流砖的同时增大溢流砖上表面倾斜角度,适当降低入口压力,同时适当增大玻璃黏度,使玻璃在溢流砖上表面分布更加均匀。

 

 Numerical simulation of molten glass flowing over the trough was carried out using FLUENT software based on the semi–implicit method for pressure–linked equations and the volume of fluid method. The effect of trough length, upsurface tilt angle of trough as well as inlet pressure and viscosity of molten glass on the flow patterns during overflow process was investigated. The simulation results showed that, in the design of advanced generation isopipe, with the increase of trough length, increasing the tilt angle of trough surface and the viscosity of molten glass, appropriately reducing the inlet pressure, could obtain a desired overflow mass distribution.
