      Analytic models of heterogenous magnetic fields for liquid metal flow simulations 

      Votyakov, E. V.; Kassinos, Stavros C.; Albets-Chico, X. (2009)
      A physically consistent approach is considered for defining an external magnetic field as needed in computational fluid dynamics problems involving magnetohydrodynamics (MHD). The approach results in simple analytical ...

      Core of the magnetic obstacle 

      Votyakov, E. V.; Kassinos, Stavros C. (2010)
      Rich recirculation patterns have been recently discovered in the electrically conducting flow subject to a local external magnetic termed "the magnetic obstacle" (E.V. Votyakov, Y. Kolesnikov, O. Andreev, E. Zienicke, and ...

      Direct numerical simulation of turbulent liquid metal flow entering a magnetic field 

      Albets-Chico, X.; Grigoriadis, D. G. E.; Votyakov, E. V.; Kassinos, Stavros C. (2013)
      This paper presents direct numerical simulations (DNS) of fully developed turbulent liquid-metal flow in a circular duct entering a magnetic field. The case of a magnetohydrodynamic flow leaving a strong magnetic field has ...

      Effects of the consistency of the fringing magnetic field on direct numerical simulations of liquid-metal flow 

      Albets-Chico, X.; Votyakov, E. V.; Radhakrishnan, H.; Kassinos, Stavros C. (2011)
      We investigate the effects of the consistency of strong fringing decreasing magnetic fields on numerical simulations of classical experimental data. Studies about fringing magnetic fields have attracted the attention of ...

      Immersed boundary method for the MHD flows of liquid metals 

      Grigoriadis, D. G. E.; Kassinos, Stavros C.; Votyakov, E. V. (2009)
      Wall-bounded magnetohydrodynamic (MHD hereafter) flows are of great theoretical and practical interest. Even for laminar cases, MHD simulations are associated with very high computational cost due to the resolution ...

      On the analogy between streamlined magnetic and solid obstacles 

      Votyakov, E. V.; Kassinos, Stavros C. (2009)
      Analogies are elaborated in the qualitative description of two systems: the magnetohydrodynamic (MHD) flow moving through a region where an external local magnetic field (magnetic obstacle) is applied and the ordinary ...
