Magnetohydrodynamic flow and heat transfer of non-Newtonian power-law nanofluid over a rotating disk with Hall current

This work studies the flow and heat transfer of a power-law nanofluid in the presence of an axial uniform magnetic field in the vicinity of a constantly rotating infinite disk. The Hall current effect is taken into consideration. The governing momentum and energy equations are solved numerically by the shooting method. Some of the results obtained for a special case of the problem are compared to the results published in a previous work and are found to be in excellent agreement. The effects of the solid fraction, the f magnetic interaction number M, the Hall current m, and the viscosity index n on the velocity and temperature profiles as well as the local skin friction coefficients and the heat transfer rate are shown graphically.
