    • A numerical evaluation of the effect of the electro‐magnetic force on bubble flow in aluminium smelting process 

      Feng, Yuging; Witt, Peter J.; Zhao, Zhibin; Zhang, Kaiyu; Schwarz, M. Philip; Wang, Zhaowen (SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)
      This paper aims to investigate the effect of electromagnetic forces on bubble flow under an anode using a computational fluid dynamics (CFD) model with the volume-of-fluid (VOF) method to capture the gas-liquid interface. ...

    • A six chemical species CFD model of alumina reduction in a Hall-Héroult cell 

      Witt, Peter J.; Feng, Yuqing; Snook, Graeme A.; Eick, Ingo; Cooksey, Mark (SINTEF Proceedings;1, Chapter, 2015)
      The industrial process for producing primary aluminium metal is the reduction of powdered alumina in a Hall-Héroult reduction cell. These cells operate at temperatures above 940 °C with a highly corrosive electrolyte making ...

    • Bubble generated turbulence in two fluid simulation of bubbly flow 

      Schwarz, M. Philip; Feng, Yuqing; Witt, Peter J. (SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)
      Bubbly flows are central to many processes in the minerals extraction and metal production industries, mainly because they enhance heat and mass transfer rates. These transfer rates depend on the turbulence level in the ...

    • Modelling thermal effects in the molten iron bath of the HIsmelt reduction vessel 

      Witt, Peter J.; Feng, Yuqing; Davis, Mark P. (SINTEF Proceedings;1, Chapter, 2015)
      Over a thirty year period the HIsmelt process has been developed as an alternative to the traditional blast furnace for the production of pig iron. This process involves the injection of fine iron ore and non-coking coal ...

    • Towards a coupled multi-scale, multi-physics simulation framework for aluminium electrolysis 

      Einarsrud, Kristian Etienne; Eick, Ingo; Bai, Wei; Feng, Yuqing; Hua, Jinsong; Witt, Peter J. (Peer reviewed; Journal article, 2017)
      Aluminium metal production through electrolytic reduction of alumina in a cryolite bath is a complex, multi-physics, multi-scale process, including magneto-hydrodynamics (MHD), bubble flow, thermal convection, melting and ...
