Influence of various hydrodynamic regimes in a melt on a solidification interface
نویسندگان
چکیده
The influence of various convective levels in a melt on a S/L interface is experimentally investigated in a continuous way from pure laminar flows to turbulent ones. Simple description in the Fourier space makes apparent a chaotic and oscillating zones alternance when thermal field is progressively increased. A classical theoretical transition towards the chaos (Feigenbaum mechanism) seems to be identified. Influence on crystal growth is finally examined. Revue Phys.

متن کاملNatural convection solid/liquid phase change in porous media
A combined numerical and experimental study is reported of solid/liquid phase change in porous media with natural convection in the melt region. The model is based on volume averaged transport equations, while phase change is assumed to occur over a small temperature range. Experiments are performed in a vertical, square enclosure using gallium and glass beads as the fluid and the porous matrix...

متن کاملModelling of dendritic growth in ternary alloy solidification with melt convection
A two-dimensional lattice Boltzmann-cellular automaton model is coupled with the CALPHAD (Calculation of Phase Diagrams) method for simulating dendritic growth during ternary alloy solidification with convection. In the model, the kinetics of dendritic growth is determined by the difference between the equilibrium liquidus temperature and the actual temperature at the solid/liquid interface, in...
متن کاملA Fixed-Grid Front-Tracking Algorithm for Solidification Problems. Part II - Directional Solidification with Melt Convection
A numerical study of directional solidification has been performed using a fixed-grid front-tracking algorithm. The directional solidification of pure tin, as well as the horizontal Bridgman growth of pure succinonitrile, were investigated. In both cases, the growth front was stable and non-dendritic, but was significantly distorted by the influence of convection in the melt and, for the Bridgm...
