Abstract
This investigation is concerned with the flow and heat transfer analysis between two disks rotating about non-coaxial axes normal to the disks. The constitutive equation of an incompressible Sisko fluid is used. The fluid is electrically conducting and the Hall effect is taken into account. Analytic solutions of the governing nonlinear problem is obtained by homotopy analysis method (HAM). The graphs are presented and discussed. Finally a comparison is made between the results of viscous and Sisko fluids
