Some Aspects of Forced Convection Nanofluid Flow over a Moving Plate in a Porous Medium in the Presence of Heat Source/Sink

Abstract

In the present paper heat transfer characteristics for boundary layer forced convective nanofluid flow past a moving plate parallel to a moving stream embedded in a porous medium in the presence of heat source/sink are analyzed. A single-phase fluid model for nanofluid is used. The governing nonlinear partial differential equations are transformed into nonlinear ordinary differential equations by means of similarity transformations and then the reduced ordinary differential equations are solved numerically by a shooting technique. The effects of different parameters on velocity, velocity gradient, temperature and temperature gradient for nanofluid with Cu and Ag as nanoparticles are presented and analyzed graphically. For the validation of the numerical scheme, the numerical results obtained in this study are compared with the published data. From the results it is cleared that dual solutions exist when the plate and the free stream move in the opposite directions.
