We present the results of velocity measurements obtained by ultrasonic Doppler velocimetry and local potential probes in the flow of GaInSn eutectic melt driven by a two-phase inductor in a cylindrical container. This type of flow is expected in a recent modification to the floating zone technique for the growth of small-diameter single intermetallic compound crystals. We show that the flow structure can be changed from the typical two toroidal vortices to a single vortex by increasing the… 

Scaling and dimensional analysis of acoustic streaming jets

This paper focuses on acoustic streaming free jets. This is to say that progressive acoustic waves are used to generate a steady flow far from any wall. The derivation of the governing equations

Model Experiments for Flow Phenomena in Crystal Growth

The concept of a physical model experiment is introduced and discussed in the context of melt and gas flows in bulk crystal growth processes. Such experiments allow one to "extract" selected physical

Computational Modelling and Electromagnetic-CFD Coupling inCasting Processes.

Many of the processes used in thesteelmaking industry (e.g. ingot casting,continuous casting, …) can lead todefects: macro-segregation, poormicrostructure properties, surfacedefects. These issues can



Turbulent stirring in an experimental induction furnace

This paper describes an experimental study of the electromagnetic stirring in a mercury induction furnace. The 200 mm-diameter furnace is supplied with a single-phase electric current of frequency

Fluid dynamical aspects of the levitation-melting process

When a piece of metal is placed above a coil carrying a high frequency current, the induced surface currents in the metal can provide a Lorentz force which can support it against gravity; at the same

Design of Two-Phase Inductor Circuit for the Floating-Zone Crystal Growth

The present work is concerned with the growth of small-diameter single intermetallic compound crystals by the floating-zone method using a radio frequency(RF)induction heating.In order to maintain a

Flow mapping of the mercury flow

Abstract An ultrasonic velocity profile (UVP) method has been successfully applied to the investigation of mercury flow contained in a stainless steel wall in the configuration of a liquid metal

Multiphase electromagnetic stirring of low conducting liquids

Purpose – To produce a controlled stirring in a low conducting liquid thanks to a new kind of multiphase inductor.Design/methodology/approach – An experimental pilot consisting of a cylindrical salt

Analytical and numerical aspects of the electromagnetic stirring induced by alternating magnetic fields

The dynamic effects of an alternating magnetic field on containers of conducting fluid are investigated in two special cases: (i) an infinitely long circular cylinder in a uniform magnetic field
