| Description
| - The aim of this paper is to present new knowledge and experience from numerical and physical modelling of metallurgical processes at the Department of Metallurgy, VSB – Technical University of Ostrava in Czech Republic and to explain especially the principle of tundish process simulations. The numerical modelling was realized by the CFD program FLUENT. This professional modelling software enables numerous settings. The paper describes the pre-processing, processing and post-processing phases of numerical modelling. The mesh of the tundish was designed by the GAMBIT software. The boundary conditions were set according to the needs of experiment. The low-Reynolds k-epsilon model was used for final computation of steel flow. The post-processing data evaluation is also discussed. Physical simulation of tundish metallurgy processes utilizes a pair of conductivity and temperature probes situated in the determined areas of the tundish model. The first pair is placed in the inlet area (shroud nozzle) and others are in the outlet zones (submersion nozzles). The probes response to the KCl concentration change after its injection into the water bath. Time delays between response at the inlet and individual outlets registration of concentration change are observed. Also, the RTD (Residence Time Distribution) curves are plotted on the basis of time dependency of concentration changes during experiments for individual outlets. Two basic methods exist of utilization of KCl concentration change in this “water” physical tundish modelling methodology.
