On the MHD and slip flow over a rotating disk with heat transfer

Purpose - To study the steady magnetohydrodynamic (MHD) flow of a viscous, Newtonian and electrically conducting fluid over a rotating infinite disk with slip boundary condition. Design/methodology/approach - The governing equations, which are partial and coupled, are transformed to ordinary ones by utilizing the similarity variables introduced by Karman and the resulting equation system is solved by using differential transform method. Findings - It is observed that both the slip factor and the magnetic flux decrease the velocity in all directions and thicken the thermal boundary layer. Originality/value - This paper studies the combined effects of slip and magnetic flux to the flow and thermal fields over a rotating single free disk in an ambient fluid, which were never studied together before.
