Abstract
The magnetohydrodynamic (MHD) mixed convection heat transfer in a non-Newtonian Powell-Erying fluid flow due to an exponentially shrinking
porous sheet is investigated. Both assisting and opposing flows are considered. After use of the suitable transformations, the governing equations
become non-similar ODEs. Numerical computations of resulting equations are obtained by very efficient shooting method for several values of
involved parameters. The results exhibit that dual non-similar solutions can be found only when some amount of fluid mass is sucked from the flow
field through the porous sheet. Many important results on the effect of external magnetic field on mixed convective flow of Powell-Erying fluid have
been explored. Where, it is found that dual non-similar solutions exist for the opposing flow, while for the assisting flow, solution is unique and for
steady Powell-Erying fluid flow stronger mass suction is required compared to the Newtonian fluid flow.
