Abstract :
In this paper, convective heat transfer and entropy generation of ZnO-EG nanofluid flow through a
square microchannel are numerically investigated. Flow is modelled by using Eulerian-Eulerian two
phase flow model. Nanoparticle volume fraction of ZnO-EG nanofluid ranged between %1.0 and %4.0.
As a result, it is found that the convective heat transfer coefficient of flow increased from 9718.15
W/m2K to 23010.79 W/m2K when 4.0% ZnO nanoparticle addition to pure EG at Re=100. Total entropy
generation of ZnO-EG nanofluid decreases with increase in nanoparticle volume fraction of ZnO-EG
nanofluid. It is also observed that the Bejan number decreases with increase in nanoparticle volume
fraction of ZnO-EG nanofluid.
