Abstract: In the ultra-wide OLED display glass forming process, for the multi-physical field coupling and bubble dynamics of the molten glass liquid transport process, this study uses the Fluent numerical simulation system to investigate the influence of temperature-viscosity effect on the flow characteristics of the glass liquid as well as the movement law of the bubbles in the channel. Considering the temperature-viscosity relationship, the internal pressure change of the system is large, and the total differential pressure increases by 40%-50% compared with the isothermal condition; the speed is less affected by the temperature-viscosity relationship, which is negligible. The larger the bubble is the easier it is to move away from the flow field towards the upper wall, inducing local vortices, and the stronger the perturbation effect on the flow field. As the bubble concentration increases, the spacing between bubbles decreases and the interference between them increases, causing turbulence in the flow field.
