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. © 2019 Isfahan University of Technology.eninfo:eu-repo/semantics/openAccessEntropy generationEthylene glycolEulerianMicrochannelNanofluidTwo-phaseLaminar forced convection and entropy generation of ZnO-ethylene glycol nanofluid flow through square microchannel with using two-phase Eulerian-Eulerian modelArticle10.29252/jafm.75.253.287442-s2.0-85058668395101Q3112
