Analytical solution for Hall and Ion-slip effects on mixed convection flow of couple stress fluid between parallel disks

The Hall and Ion-slip effects on fully developed electrically conducting couple stress fluid flow between parallel disks has been considered. The governing non-linear partial differential equations are transformed into a system of ordinary differential equations using similarity transformations and then solved using Homotopy Analysis Method (HAM). The effects of the magnetic parameter, Hall parameter, Ion-Slip parameter, Prandtl number and couple stress fluid parameter on velocity and temperature are discussed and shown graphically.
