In magnetohydrodynamic (MHD) flows turbulence reduction occurs due to the Joule dissipation. It
results in heat transfer degradation. In open channel flows, heat transfer degradation is also caused by the
turbulence redistribution near the free surface. Both effects can be significant in fusion applications with
low-conductivity fluids such as molten salts. In the present study, the ``Ke'' model equations for turbulent
flows and the free surface boundary condition are adjusted with taking into account MHD effects. Different
