• 3D squeezing MHD nanofluid flow in a rotating channel on a porous wall is considered.
• Navier-Stokes equations are normalized by appropriate similarity transformations.
• Variational Iteration Method (VIM) was applied for finding the analytical solution.
• Results demonstrate that nanoparticle additives have significant effects on the flow.
A new analytical approach has been performed by using both similarity transformation and Variational Iteration Method (VIM) on the silver, copper, copper oxide, titanium oxide and aluminum oxide nanofluids flowing through a rotating channel with lower stretching porous wall under the squeezing magnetohydrodynamic (MHD) flow conditions. The effects of nanoparticles concentration, characteristic parameter of the flow, suction parameter and magnetic parameter are investigated on the velocity profiles and the shear stresses at lower and upper walls. The results show significant influence of nanoparticle additives on the shear stress and skin friction coefficient of the flow at the walls. The analytical results are compared with those obtained by numerical solution and remarkable agreement is achieved.
