3D numerical simulation and experimental investigation of pure tin solidification under natural and forced convection

The numerical simulation of the horizontal solidification pure tin under natural convection and forced induced by Electromagnetic Stirring (EMS) is presented compared with experimental results obtained ‘AFRODITE’ benchmark setup, described in several previous publications [6–10]. experiment consists solidifying a rectangular ingot (100 × 10 60 mm) using two lateral heat exchangers which allow application controlled temperature difference. difference between sides sample DT = 40 K cooling rate CR −0.03K/s. Under these conditions front planar throughout experiment. Enthalpy formulation based on fixed-grid techniques used for simulations phase-change problems, accounting buoyancy created Lorentz forces generated an external Traveling Magnetic Field (TMF). distribution demonstrated to effectively reproduce maps from measurements. proposed 3D model has its effectiveness predicting effect EM stirring process terms thermal field, dynamic field shape localization front.
