The kinetics of dendritic solidification is driven by the combined effects of heat transfer, solute transport, and surface tension. In addition, convection can play a large role in heat and solute transfer near the solidifying interface and can affect the resulting microstructure. A Phase Field (PF) - Lattice Boltzmann (LB) model is developed to numerically simulate dendritic growth during solidification of binary alloys. The Lattice Boltzmann method is used to simulate transport phenomena by solving the discrete Boltzmann equation. The Phase Field method is used to model the evolution of the solid/liquid interface. Dendritic growth is studied under terrestrial conditions where natural convection exists and compared to dendritic growth in space where the effects of gravity are negligible.
