laminar forced convection and entropy generation of zno-ethylene glycol nanofluid flow through square microchannel with using two-phase eulerian-eulerian model

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.
