NUMERICAL-SIMULATION OF UNSTEADY COLOR-CHANGE IN GLASS MELTING TANK

Melting glass furnace mathematical modelling currently includes couple d simulations of electrical boosting, bubbling, flame radiation, etc.. . Increasing modelling complexity may also result from consideration o f unsteady solutions. Different sources of thermoconvective unsteadine ss can be considered: pull modification, time variation of bubbling an d/or boosting, shift of the temperature profile or, finally, colour ch ange [1], this paper will present the numerical solutions to the last unsteady coupled mixing problem.
