Effect of the Impeller Design on Degasification Kinetics Using the Impeller Injector Technique Assisted by Mathematical Modeling

摘要: A mathematical model was developed to describe the hydrodynamics of a batch reactor for aluminum degassing utilizing rotor-injector technique. The uses Eulerian algorithm represent two-phase system including simulation vortex formation at free surface, and use RNG k-e account turbulence in system. employed test performances three different impeller designs, two which are available commercially, while third one is new design proposed previous work. simulates consequently helps explain connect terms kinetics gas consumption found physical modeling previously reported. Therefore, water model. reveals that distributes bubbles more uniformly throughout ladle, exhibits better-agitated bath, since transfer momentum fluids better. Gas evenly distributed with this because both phases, liquid, dragged bottom ladle as result higher pumping effect comparison commercial designs.
