Abstract
Phase field model is known to be very powerful in describing the complex pattern formation of the interface in non-equilibrium state, such as growth of dendritic crystals. In this study, the effects of anisotropy of the crystals on Mullins-Sekerka instability in growth of solid-liquid interface were investigated numerically. Given the sign curves at the solid-liquid interface in supercooled state, the growth of the interface was simulated using phase field model. The direction of the anisotropy of the crystals, the intensity of the anisotropy and the surface tension were varied as the parameters, and the conditions at which the amplitude of the curves increases were picked up.
