  • [PDF] CFD simulation of free surface flow and heat

    Molten slag is atomised by a spinning disc into droplets that are quenched via cold air to produce glassy slag granules. Steady-state two-dimensional CFD simulations of the multiphase flow and heat transfer in the slag and air were carried out. Also considered in the CFD model is conjugate heat transfer between liquid slag, solidified slag and the disc.
