Unsteady 3D Numerical Simulation Of Glass Melting Tank: Colour Change

Melting glass furnace mathematical modelling currently includes coupled simulations of electric boosting, bubbling, flame radiation, etc. Increasing modelling complexity may also result from the consideration of unsteady solutions. Different sources of thermoconvective unsteadyness can be considered: pull modification, time variation of bubbling and/or boosting, shift of the temperature profile or, finally, colour change. Motivated by the industrial interest of accurate representation of colour change, this paper will present the numerical solutions to this last unsteady coupled mixing problem.
