Abstract

A study of non-Newtonian Sutterby ferrofluid and heat and mass transfer in the flow due to curved stretching sheets is presented.The flow in porous media is described using the Darcy-Forchheimer model which caused by the linear velocity of the curved stretching sheet. Concentration and energy equations are incorporated in the study of mass and heat transfer impacts. The motile microorganism equation included governing the swimming of the gyrotactic microorganism. The governing equations are transformed from nonlinear partial differential equation to ordinary differential equation and the solved using Homotopy Analysis method. The velocity is reduced due to dipole and non-Newtonian parameters effects. Temperature increases with the magnetic dipole and thermal radiation parameters. Concentration decreases with an increase chemical reaction parameter and the concentration of microorganisms decreases with the Lewis number  and increase with Peclet number. Streamlines show that trapping on the curved stretched surface is uniform.
