Abstract: The combined effects
of viscous dissipation and Joule heating on steady magnetohydrodynamics (MHD)
and slip flow of an electrically conducting viscous incompressible non-Newtonian
Bingham fluid over a porous rotating disk in the presence of Hall and ion-slip
currents are studied. An external uniform magnetic field is applied in the z-direction
and the fluid is subjected to uniform suction. Numerical solutions are obtained
for the governing momentum and energy equations. Results for the details of the
velocity as well as temperature are shown graphically and the numerical values
of the skin friction and the rate of heat transfer are entered in tables. |
Keywords and phrases: rotating disk, Bingham fluid, Joule heating, viscous dissipation, ion-slip currents. |
