Abstract: The Nusselt number, overall heat transfer, and convective heat transfer coefficients of glycerol-water-based Cu nanofluids flowing in a parallel flow double pipe heat exchanger are estimated using CFD analysis. Single-phase fluid approach technique is used in the analysis. Ansys 19.0 workbench was used to create the heat exchanger model. Heat transfer tests with nanofluids at three flow rates (680<re<1900) are=”” carried=”” out=”” in=”” a=”” laminar=”” developing=”” flow=”” zone.=”” for=”” testing,=”” 500=”” mm=”” long=”” concentric=”” double=”” pipe=”” heat=”” exchanger=”” with=”” tube=”” dimensions=”” of=”” id=”10.2″ mm,=”” od=”12.7″ and=”” annulus=”” is=”” employed.=”” copper=”” utilized=”” the=”” material.=”” this=”” study=”” employed=”” three-particle=”” volume=”” concentrations=”” 0.2=”” percent,=”” 0.6=”” 1.0=”” percent.=”” mass=”” rates=”” hot=”” water=”” 0.2,=”” 0.017,=”” 0.0085=”” kg=”” s,=”” while=”” nanofluids=”” 0.03,=”” 0.0255,=”” 0.017=”” s.=”” average=”” temperature=”” 36°c,=”” whereas=”” 58°c.=”” comparison=”” to=”” base=”” liquid,=”” overall=”” transfer=”” coefficient=”” convective=”” htc=”” percent=”” at=”” 0.03=”” s=”” raised=”” by=”” 26.2=”” 46.2=”” respectively.=”” experimental=”” findings=”” compared=”” cfd=”” values,=”” they=”” close=”” agreement.<=”” span=””></re<1900)>
