Large eddy simulation of MHD turbulent Taylor-Couette flow in axial magnetic field

We conduct large eddy simulation of magnetohydrodynamic (MHD) turbulent Taylor-Couette (TC) flows in the axial magnetic filed. The Hartmann number is proportional to the magnetic flux density. We investigate the effect of the Hartmann number on the flow and electric current fields. As increasing the Hartmann number, turbulent fluctuations are suppressed, and the turbulent flow distributions approach the MHD laminar flow distributions. The orientations of turbulent vortices change from the azimuthal flow direction to the axial magnetic field direction. The triplet high-speed streaky structures emerge near the inner wall.
