Heat transfer analysis of GO-water nanofluid flow between two parallel disks

Abstract

In this paper, the unsteady magnetohydrodynamic (MHD) squeezing flow between two parallel disks (which is filled with nanofluid) is considered. The Galerkin optimal homotopy asymptotic method (GOHAM) is used to obtain the solution of the governing equations. The effects of Hartman number, nanoparticle volume fraction, Brownian motion parameter and suction/blowing parameter on nanofluid concentration, temperature and velocity profiles have been discussed. Furthermore, a comparison between obtained solutions and numerical ones have been provided.
