Electrical boosting is used to improve the circulation characteristics of the glass melt and augment the heat transfer from the combustion space to the molten glass. The effect of electric boosting in a glass furnace is simulated with CFD by solving the real and imaginary parts of the electric potential and coupling the resulting Joulean heat dissipation as a source term to the energy equation of the glass melt. The user can choose the location and configuration of the electrodes and has the flexibility to match the total power input to the glass tank by either adjusting the applied voltage to the electrodes or updating the electric current field.

Contours of the real voltage on the walls of the glass tank and the electrodes and the pathlines of particles injected from the inlet.
