Nanofluid Flow and Heat Convection in a Channel Filled with Porous Medium

Abstract

The nanofluid flow and heat convection in a horizontal
parallel-plates channel filled with porous medium is investigated.
The upper plate of the channel is considered porous, subjected with
a constant suction while there is no cross-flow at the lower plate.
Flow and heat convection in the channel is influenced by a static
transverse magnetic field by means of Lorenzian force and Joule
heating effect. The velocity and temperature profiles are derived by
differential transform method (DTM), computed and discussed
through graphs. Convection of heat in the nanofluids AL2O3/H2O,
Cu/H2O and Ag/ H2O are compared in terms of Nusselt number and
investigated the effects of various physical parameters Reynolds
number, Hartmann number and Prandtl number. The skin-friction
coefficients at the plates are also calculated and discussed through
graphs.
