Abstract

Magnetohydrodynamic turbulent shear flows at low magnetic Reynolds number are studied by using a two-scale direct-interaction approximation combined with the double expansion with regard to the magnetic Reynolds number and the interaction parameter. Using these statistical results, a two-equation turbulence model which incorporates the effects of magnetic fluctuations is constructed. This model can quantitatively explain existing experimental results for the skin friction in MHD channel flows.
