Part I. Implementation and verification of model

verfasst von: Sergejs Spitans, Andris Jakovics, Egbert Baake, Bernard Nacke
Abstract: By means of ANSYS Classic and ANSYS CFX external coupling, a numerical model for free surface dynamics of electrically conductive fluid in an alternate electromagnetic field is developed. Volume of Fluid (VOF) numerical technique and k-ω SST turbulence model are applied for the high Reynolds number two-phase flow calculation. The model is extended on 3D and adjusted for the case of electromagnetic levitation. Results for the steady-state free surface shapes obtained with transient calculations are compared with other models and experimental measurements in induction furnaces, induction furnace with cold crucible, and electromagnetic levitation melting device. Numerical calculation results of free surface dynamics are compared with analytic estimation of free surface oscillation period. Parameter studies by means of developed approach and comparison between 3D simulations of free surface dynamics of electromagnetically induced flow with k-ω SST and large eddy simulation (LES) turbulence models are discussed in the second part of the article to follow.
