COMBINED EFFECT OF HEAT AND MASS TRANSFER IN MHD FLOW OF A NANOFLUID BETWEEN EXPANDING/CONTRACTING WALLS OF A POROUS CHANNEL
ABSTRACT
We consider an incompressible laminar viscous nanofluid in a porous channel with expanding/contracting walls. The governing equations of flow and heat transfer are reduced into a set of nonlinear coupled ordinary differential equations (ODEs). A combination of an iterative (successive over relaxation) and a direct method is employed for solving the sparse systems of linear algebraic equations arising from the finite difference discretization of the linearized self-similar ODEs. We have noticed that the permeability Reynolds number increases both the shear stress and the heat transfer rate when the porous walls of the channel are moving away, whereas the viscous dissipation always increases the heat transfer rate at the walls, irrespective of the wall movement.
