Dynamics of dendrite growth in a binary alloy with magnetic field effect
Résumé
In order to analyze the dynamical changes in the free dendritic growth due to magnetic- field, we have developed a 2D phase- field model which consists of nonlinear evolutive and coupled systems of flow, concentration and phase field in an isothermal environment. We present the realistic numerical simulations of the influence of various magnetic- fields and other critical parameters of the derived model on the evolution of dendrites during the solidifi cation of the binary mixture of Nickel-Copper (Ni-Cu).
