Effects of flow on morphological stability during directional solidification
Research involving the interaction of flow with morphological instability during directional solidification of binary alloys is reviewed. In general, flow may arise during the solidification process from thermal and solutal buoyancy, changes in density upon solidification, thermocapillary forces at free boundaries, or external forcing of the system. We focus primarily on the last of these, givi...
متن کاملModelling of physical phenomena on Si melt during crystal growth process by Directional solidification method
Numerical simulation is a comprehensive tool in modern process development which is extensively used for promotion of crystal growth processes. Multi-crystalline silicon is an important material with advantages of low-production cost and high conversion efficiency of PV solar cells. The control of grains as well as the grain boundaries is particularly important to the crystal quality and thus t...
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...
متن کاملUltrasonic Sensing of Solid-Liquid Interface during Directional Solidification of Aluminum
This paper presents a newly developed high temperature ultrasonic sensor and its application to in situ observation of aluminum (Al) alloy during solidification and melting in temperature up to 800C. The ultrasonic sensor mainly consists of a conventional piezoelectric transducer, a titanium buffer rod as an acoustic waveguide and an air cooling pipe. The length is approximately 300 mm. This ul...
متن کاملInfluence of various hydrodynamic regimes in a melt on a solidification interface
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 b...
