Influence of rotor shape on the flow dynamics in degassing ladles was studied. Gas injection decreased liquid velocity magnitudes for the commercial rotors. Pumping capacities are found higher in radial direction than in axial direction. At high gas flow rate, commercial rotors show a notable diminishing in turbulence. The novel impeller presents the best performance at different gas flow rates.
