Abstract

In the present paper, based on the two-phase model (Eulerian-Eulerian model), the three-dimensional fluid flow in water system and liquid steel system stirred by one or two gas jets is simulated. A new modified k-ε turbulence model is introduced to consider the bubbles movement contribution to k and ε. The mathematical simulation agrees well with the experimental results. Calculation indicates that the distance of the two jet nozzles has a big effect on the fluid flow behaviour. Placing two gas injection nozzles at the half radii of one diameter of the bottom generates a much better mixing than that injected by only one nozzle with the same total gas flow rate.
