4. 2. Modeling of magnetohydrodynamic turbulence

   Author : Ola Widlund; KTH; []
   Keywords : turbulence model; magnetohydrodynamic; mhd; magnetohydrodynamic turbulence; computational fluid dynamics; continuous casting;

   Abstract : Conventional one-point turbulence closures have beenextended with an additional transported scalar for modeling ofmagnetohydrodynamic (MHD) turbulence. The new scalar, α ,captures the length scale anisotropy and tendency towardstwo-dimensionality, which is characteristic feature of MHDturbulence, and allows accurate modeling of the Jouledissipation of turbulence.
