Paper presented at the 5th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, South Africa, 1-4 July, 2007.
This study presents a numerical simulation of the
convective laminar flow, driven by combined thermo-solutally
buoyancy forces, under a uniform horizontally applied
magnetic field, held during the solidification of a molten alloy
Al- 4.1wt%Cu filled in a rectangular cavity. The continuum
model, of Bennon and Incropera , was used in the
development of the mathematical model, representing the
solidification phenomena. Following this model, the alloy
solidification process is governed by continuity, Navier-Stokes,
energy, species and electrical potential conservation equations.
Here solved by using finite volume method. The effect intensity
of the magnetic field on convective flow has been investigated.
The governing equations are firstly non-dimensionalized and
are approximated by using a finite volume method.
