Abstract The homogeneous model was used to study the fluid flow in RH reactor with different parameters of immersion tubes. While the immersion tubes are located eccentrically, larger eddies appear near the down immersion tube at the bottom of vacuum chamber, under free surface of vacuum chamber and in ladle, but no obvious effect on the recirculation flow rate was observed. While the distance between two tubes is decreased, the recirculation flow rate decreases, and the recirculation near the left wall of the vacuum chamber is enhanced. The recirculation flow rate increases with the immersion depth. In order to increase the recirculation flow rate, either the immersion depth of immersion tubes should be reduced or the distance between immersion tubes,should be increased and if slag entrapment should be avoided at same time.
