Rotating disk flow and heat transfer of a conducting non-newtonian fluid with suction-injection and ohmic heating
The steady hydromagnetic flow in a porous medium of an incompressible viscous electrically conducting non-Newtonian fluid above an infinite rotating porous disk is studied with heat transfer. An external uniform magnetic field is applied perpendicular to the disk and a uniform injection or suction is applied through the surface of the disk. Numerical solutions of the nonlinear governing equations, which govern the flow and energy transfer, are obtained. The effect of the magnetic field, the suction and injection velocity and the characteristics of the non-Newtonian fluid on the velocity and temperature distributions are considered.
