| 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‐? turbulence model is introduced to consider the bubbles movement contribution to k and ?. 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. |
