 abstract = {A magnetic field, imposed on turbulent flow of an electrically conductive fluid, is known to cause preferential damping of the velocity and its fluctuations in the direction of Lorentz force, thus leading to an increase in stress anisotropy. Based on direct numerical simulations (DNS), we have developed a model of magnetohydrodynamic (MHD) interactions within the framework of the second-moment turbulence closure. The MHD effects are accounted for in the transport equations for the turbulent stress tensor and energy dissipation rate-both incorporating also viscous and wall-vicinity nonviscous modifications. The validation of the model in plane channel flows with different orientation of the imposed magnetic field against the available DNS (Re=4600,Ha=6), large eddy simulation (Re=2.9?104,Ha=52.5,125) and experimental data (Re=5.05?104 and Re=9?104, 0?Ha?400), show good agreement for all considered situations. ? 2004 American Institute of Physics.},
