    • Metamodeling of the Electrical Conditions in Submerged Arc Furnaces 

      Sparta, Manuel; Varagnolo, Damiano; Stråbø, Kristian; Halvorsen, Svenn Anton; Herland, Egil Vålandsmyr; Martens, Harald Aagaard (Peer reviewed; Journal article, 2021)
      Physics-based Finite Element Methods models can be used to investigate the electrical conditions in submerged arc furnaces (SAFs). However, their explicit solution may be very demanding in terms of time and computational ...

    • Reduced 2D/1D mathematical models for analyzing inductive effects in submerged arc furnaces 

      Fromreide, Mads; Gomez, Dolores; Halvorsen, Svenn Anton; Herland, Egil Vålandsmyr; Salgado, Pilar (Peer reviewed; Journal article, 2021)
      Mathematical models have been developed to investigate the quantitative behaviour of the current and power distributions in large submerged arc furnaces, usually fed by a low-frequency alternating source. Reduced 2D and ...

    • Skin and Proximity Effects in Electrodes and Furnace Shells 

      Herland, Egil Vålandsmyr; Sparta, Manuel; Halvorsen, Svenn Anton (Peer reviewed; Journal article, 2019)
      A review of two-dimensional (2D) analytical models of skin and proximity effects in large industrial furnaces with three electrodes arranged in an equilateral triangle is given. The models cover three different cases: one ...

    • Understanding Scale-Up of High-Current Electrodes 

      Halvorsen, Svenn Anton; Herland, Egil Vålandsmyr; Sparta, Manuel; Risinggård, Vetle Kjær (Peer reviewed; Journal article, 2023)
      A simple and generic model for the heat distribution in electrodes for primary metal production has been investigated. The equations have been analyzed focusing on understanding the scale-up of electrodes under both direct ...
