Abstract
The three-dimensional numerical simulation of the glass melt flowing out from the slit was conducted by Semi-Implicit Method for Pressure Linked (SIMPLE) and volume of fluid (VOF) method with the software FLUENT. In this work, the effect of liquid level of glass melt, viscosity of glass melt, width and height of the slit on flow rate was investigated. The simulation results showed that the flow of glass melt was proportional to the height of the liquid surface and the square of the slit width, and inversely proportional to the viscosity of the glass melt and the height of the slit. It was concluded that high liquid level and low viscosity should be adopted in the drawing process of the flexible glass sheet.
