Analytical solution of mixed convection flow of couple stress fluid between two circular cylinders with Hall and ion-slip effects

This paper presents the Hall and ion-slip effects on electrically conducting couple stress fluid flow between 2 circular cylinders in the presence of a temperature dependent heat source. The governing non-linear partial differential equations are transformed into a system of ordinary differential equations using similarity transformations and then solved using the homotopy analysis method (HAM). The effects of the magnetic parameter, Hall parameter, ion-slip parameter, and couple stress fluid parameter on velocity and temperature are discussed and shown graphically.
