Three-dimensional numerical modeling of circulation and heat transfer in a glass melting tank Part 1. Mathematical formulation

Abstract

This paper presents numerical methodology to simulate the transport processes in a glass melting tank. The model also considers the most widely used glass circulation enhancement schemes such as air bubblers and electric boosting. Refining process is simulated by predicting the size distribution and number density of gas bubbles within the glass melt. The gas bubbles are allowed to grow and dissolve within the melt. The diffusion of gas is restricted to a single component, and bubble rupture and collision are neglected. Contribution of gas bubbles to the buoyancy force is also accounted for. The numerical method of solution employed is summarized.
