Abstract: This study deals with the optimization of a cold crucible melter
where electric currents are directly induced in a glass charge. Designs of
experiments are used to determine the factors of the crucible design which have
an impact on the efficiency, and result in an optimized configuration.
Numerical tools are used to lead the experiments: a finite volume software,
used to solve hydrodynamics and thermal equations, is coupled to a finite
element software which computes the Maxwell equations. The innovation is the
use to couple directly areas treated with surface impedance and volume
formulations, in electromagnetic simulation. The optimized configuration is
then studied comparing numerical simulations and experiments in an industrial
unit.
Keywords: Coupling, design of experiments, optimization, sensitivity analysis
