Analytical solution of MHD free convective flow of couple stress fluid in an annulus with hall and ion-slip effects

Abstract

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