A numerical study was carried out to predict three dimensional turbulent flow heat and mass transfer in RH-ladles. To model the turbulence in the system, the popular Launder and Sharma (7) version of the low Reynolds number k-$ varepsilon$ model was employed. The governing equations for fluid flow and heat transfer were solved using a control volume-based finite difference method. The buoyancy effect in the axial momentum equation was incorporated through the Boussinesq approximation. From the fluid flow and turbulence characteristics predicted by the numerical model, the mass transfer occurring from the dissolution of steel rods immersed in the liquid steel was computed using the Sherwood number correlation recently proposed by Mazumdar et al. (25). The parameters studied include: the flow rate of steel, the heat flux from the solid walls and various radial positions of the vertically immersed steel rod. The fluid flow results are presented as vector plots. The heat transfer aspects are shown through temperature contours at various vertical planes and the mass transfer results are graphically presented in plots showing variance of mass transfer coefficients with key parameters. / The flow field results were found to be in qualitative agreement with previously reported 3D numerical studies for similar systems. Due to the lack of any experimental or numerical results related to heat and/or mass transfer in RH-ladles, the heat and mass transfer results obtained in the present study could not be compared and verified.
