MHD effects on turbulent dissipation process in channel flows with an imposed wall-normal magnetic field

The contribution of MHD source term derived from Lorentz force on the turbulent dissipation process is very small. However, modulation of the other terms in this process was remarkably observed with Hartmann number increasing. The turbulent dissipation process under the MHD effects is similar under the same R condition, where R is the Reynolds number based on the Hartmann layer thickness and the laminar centerline velocity.
