Natural Convection Heat Transfer in a Rectangular Enclosure With a Transverse Magnetic Field
S. Alchaar,P. Vasseur,E. Bilgen +2 more
TL;DR: In this article, the effect of a transverse magnetic field on buoyancy-driven convection in a shallow rectangular cavity is numerically investigated (horizontal Bridgman configuration), where the enclosure is insulated on top and bottom walls while it is heated from one side and cooled from the other.
Journal ArticleDOI
Numerical investigation of natural convection in a rectangular cavity under different directions of uniform magnetic field
TL;DR: In this paper, a second-order compact finite difference algorithm, involving a secondorder compact scheme for the streamfunction-velocity (ψ−−u) form of Navier-Stokes equations and a fourth-order finite difference (FDF) algorithm for the energy equation, is employed to solve the steady-state laminar magnetohydrodynamic (MHD) natural convection problems.

Effect of induced electric field on magneto-natural convection in a vertical cylindrical annulus filled with liquid potassium
Masoud Afrand,Sara Rostami,Mohammad Akbari,Somchai Wongwises,Mohammad Hemmat Esfe,Arash Karimipour +5 more
TL;DR: In this article, a vertical cylindrical annulus formed by two coaxial cylinders filled with liquid potassium is studied numerically, and the authors show that flow is axisymmetric in the absence of the magnetic field; but by applying the horizontal magnetic field, it becomes asymmetric.

Elimination of Solute Banding in Indium Antimonide Crystals by Growth in a Magnetic Field
TL;DR: In this article, the authors used a vertical dc magnetic field to damp the thermal convection in the molten sample to suppress turbulence, thereby eliminating the temperature fluctuations in the liquid that cause the solute bands.

R. Ricou,Charles Vives +1 more
TL;DR: In this paper, a probe permitting the determination of the velocity magnitude and direction at every point for a steady or time-varying state within a molten metal is described, based on an experimental study of the flow of a liquid metal around a cylindrical magnet.

Melting and solidification of a metal system in a rectangular cavity
Chie Gau,R. Viskanta +1 more
TL;DR: In this article, the role of natural convection on solid-liquid interface motion during melting and solidification of Lipowitz metal in a rectangular cavity was studied, and measurements of both temperature distributions and temperature fluctuations were used as a qualitative indication of the natural convective flow regimes and structures of melt during phase transformation.
