Simulation of heat flow in a direct-chill caster using comsol multiphysics

Melt-conditioned direct chill (MC-DC) casting process is a novel billet casting technology developed recently for enhanced the grain refinement of cast billet without any grain refiner required. Present work endeavours to understand the behaviour of various parameters of rotor-stator based shearing...
