Abstract
The present study numerically investigates the ow and heat transfer of porous Williamson hybrid nanouid on an exponentially shrinking sheet with magnetohydrodynamic (MHD) eects. The nonlinear partial dierential equations which governed the model are first reduced to a set of an ordinary differential equations by using the similarity transformation. Next, the BVP4C solver is applied to solving the equations by considering the pertinent fluid parameters such as the permeability parameter, the magnetic parameter, the Williamson parameter, the nanoparticle volume fractions and the wall mass transfer parameter. The single (SWCNTs) and multi-walled carbon nanotubes (MWCNTs) nanoparticles are taken as the hybrid nanoparticles. It is found that the increase in magnetic parameter in SWCNT + MCWNT hybrid nanofluid results to the increase of 72.2% on skin friction compared to SWCNT nanofluid while maintaining reducing a small number of Nusselt number. This shows the potential of the Williamson hybrid nanofluid as a friction application purposes especially in transportation like braking system, flushing fluid and mechanical engineering.
