The continuum model, of Bennon and Incropera [1], 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.6 pagesPDFenUniversity of PretoriaUniversity of PretoriaNumerical simulation of the convective laminarCombined thermo-solutally buoyancy forcesUniform horizontally applied magnetic fieldSolidification of a molten alloyBennon and IncroperaNavier-StokesElectrical potential conservation equationsFinite volume methodPresentation
