Mixing And Flow In Glass Tanks

Mixing influences that are effective the flow of glass through continuous tanks are classified. Common experimental techniques for evaluating these influences are compared. A multi-cell model is used to describe flow behaviour in the absence of mixing from transfer flow. Laminar transfer flow in a glass-tank is evaluated by considering flow thorough an open channel with a vertical viscosity gradient. Recently published results describing flow through a tank for container glass at relatively high rate of drawing are best explained by a secondary flows modifying the mixing effects from the variable velocity of laminar transfer flow through the tank.
