In the advanced glass melter small particles of batch materials are rapidly heated to glass formation temperatures while entrained in gas, and then deposited on a target surface. The resulting liquid slurry, consisting of sand, CaO, and MgO particles in the liquid formed by mixing of molten cullet and Na 2 CO 3 , flows down the center body. During this flow the solid particles dissolve in the liquid and diffuse to form glass. This paper describes a numerical model developed to describe the behavior of this liquid layer. The model is based on Navier‐Stokes equations reduced for the case of a low Reynolds number liquid layer flowing under the action of gravity and shear from gases flowing on top. Experimental results agree with model predictions.
