In the present work, forced convection heat transfer
were investigated numerically for the fully developed fluid flow
of incompressible viscous laminar flow (Re=50-500) under the
constant wall heat flux in sudden expansion channels. Various
fluids were used with different concentration of nanoparticle
such as TiO2, ZnO and SiO2. These nanoparticles were dispersed
with the range of 0.5-2% volume concentrations in pure water to
form stable suspensions of nanofluids. The flow assumed to be
uniform in the channel inlet and numerical computations were
performed for the fully developed laminar flow conditions.
ANSYS Fluent15.0 code, commercially available software based
on finite volume approach was used to calculate the governing
continuity, momentum and energy equations. Obtained results
from numerical study was plotted graphically and discussed in
detail. Effect of nanoparticle volume fraction and Reynolds
number on the convective heat transfer, Nusselt number,
pressure drop and Darcy friction factor were determined.
