“…The problem of simulations of magnetohydrodynamics coupled with the cal-culation of the shape of the metallic charge is not new, and has been reported, for example, in metallurgy. Employed numerical methods were based on the mesh deformation [11][12][13][14] or used the volume of fluid (VOF) models [15][16][17][18][19][20][21].…”

“…Mostly, models based on Reynolds averaged Navier-Stokes equations (RANS) are used -e.g. k- [13,14,19,20,22], k-RNG [15,23], k-ω [11,24], or k-ω SST [16,17] -and sometimes Large Eddy Simulation (LES) is used [21,23,25,26], despite the longer calculation times needed for this method. The calculations of the hydrodynamic and the electromagnetic parts are often performed sequentially and sometimes with two different software [16,20,23,25,26], allowing the use of finite elements for the electromagnetic part and finite volume for the fluid flow.…”

This article presents the numerical modeling of an in-can melter containing a metallic and a glass phase. Low-frequency electromagnetic induction is used to melt and stir the metal, and the latter heats and drags the glass phase. A careful choice of operating parameters is required to prevent the solidification of the glass, and to increase the performances of the process. Numerical modeling helps in avoiding experimental trial and error method and in studying the effect of the operating parameters on the hydrodynamics. The main difficulty for the numerical modeling comes from the deformation of the interfaces, produced by the magnetic pressure. First, a theoretical estimation of this phenomenon is performed and compared with numerical and experimental results. Then, numerical results are presented for different power inputs, AC frequencies, and quantities of glass. One of the phenomena obtained numerically is air entrainment at the triple point, creating bubbles in the glass.

“…In previous numerical studies of the research team [4], this coupling procedure was developed and examined for different operating conditions and material properties [5]. The last investigation [6], which was the most comprehensive analysis, indicated that the proposed mathematical model and coupling procedure yields reasonable accuracy in terms of the heat transfer and free surface prediction despite its simplicity.…”

The technology of mental melting in a vacuum induction furnace enables the efficient removal of impurities and provides an opportunity to melt refractory metals, such as titanium. These materials can be applied in cutting edge technologies, such as aviation (turbine blades) and biotechnology (prosthesis and implants). To control metallurgical heat and mass processes within an induction furnace, measurements and a numerical analysis can be conducted. In this paper, numerical approaches are discussed. Simulation requires the development of vacuum induction furnace coupling between fluid dynamics and electromagnetic fields. The proposed numerical domain was modelled as a threedimensional slice with a properly defined periodic boundary condition. To define the analysed electromagnetic problem, a set of Maxwell differential equations was specified. A fluid dynamics sub-model was composed of the mass and momentum conservation equations using the volume of fluid multiphase formulation, two-equation k- turbulence model and species transport to track the inclusion position within the melt. The main purpose of this study was an examination of the impurities removal process via the free surface of the melt within an induction furnace. The coupled computations were performed for five operating conditions, including different power inputs of the inductor. The results indicated a strong influence of the inductor power on the free surface area and therefore on the purification process intensity.

“…The most commonly used formulations are those based on the Reynolds-averaged Navier-Stokes (RANS) model. One paper [8] gives an analysis of the influence of different turbulence equations on the shape of the free surface of liquid metal. Turbulence intensity and its impact on the evaporation of components of the melt were examined as well [9].…”

In this paper, an accurate numerical model of coupled phenomena in an induction furnace applied in the modern metallurgy industry was formulated. In addition, an examination of material properties' influence on the melting process and the free surface shape in an induction furnace with a ceramic crucible was performed. The results showed insignificant influence of the most important properties on the free surface shape of the molten metal. Streszczenie. Celem pracy było stworzenie dokładnego modelu numerycznego sprzężonego zjawiska topienia metalu w piecu indukcyjnym oraz identyfikacja wpływu własności materiałowych ciekłego metalu na uzyskiwane wyniki. Z tego powodu przeprowadzono szereg analiz wrażliwości przepływowych oraz elektromagnetycznych własności stopionego metalu. Zaobserwowano niewielki wpływ własności materiałowych na kształt powierzchni swobodnej, co świadczy o zasadności zastosowania uproszczeń w modelach numerycznych procesów topienia metalu w piecach indukcyjnych. Dokładny model numerycznego sprzężonego zjawiska topienia metalu w piecu indukcyjnym
