On squeezing flow of nanofluid in the presence of magnetic field effects

This article investigates the magnetohydrodynamic (MHD) squeezing flow of nanofluid over a porous stretching surface. Constitutive expressions of viscous fluid are employed in the mathematical formulation. Brownian motion and thermophoretic diffusion of nanoparticles are taken into account. Fluid is electrically conducted in the presence of an applied magnetic field. The induced magnetic field is neglected for a small magnetic Reynolds number. Appropriate transformations yield a coupled nonlinear ordinary differential system. The resulting nonlinear system is solved successfully. Graphs are plotted to examine the impacts of physical parameters on the velocity, temperature and nanoparticle concentration distributions. Skin friction coefficient Nusselt and Sherwood numbers are analyzed numerically. (C) 2015 Elsevier B.V. All rights reserved.
