Effect of magnetic field direction on MHD turbulent channel flow at low magnetic Reynolds number

Direct numerical simulations (DNSs) of magnetohydrodynamic (MHD) turbulent channel flow at Ret = 180 are performed using a pseudo-spectral Navier—Stokes solver. Simulations are performed in the limit of low magnetic Reynolds number. Three cases are considered, where the magnetic field vector is directed in x, y and z directions. The significance of the magnetic field direction on the mean flow statistics are presented in comparison with the DNS data of a plane turbulent channel flow.
