Experimental and CFD Analysis of GW70 based Cu Nanofluids in a Parallel Flow Heat Exchanger

The Nusselt number, overall heat transfer, and convective transfer coefficients of glycerol-water-based Cu nanofluids flowing in a parallel flow double pipe exchanger are estimated using CFD analysis. Single-phase fluid approach technique is used the Ansys 19.0 workbench was to create model. Heat tests with at three rates (680<Re<1900) carried out laminar developing zone. For testing, 500 mm long concentric tube dimensions ID=10.2 mm, OD= 12.7 annulus ID=17.0 19.5 employed. Copper utilized for material. This study employed three-particle volume concentrations 0.2 percent, 0.6 1.0 percent. mass hot water 0.2, 0.017, 0.0085 kg/s, while 0.03, 0.0255, 0.017 kg/s. average temperature 36°C, whereas 58°C. In comparison base liquid, coefficient HTC percent copper 0.03 kg/s raised by 26.2 46.2 respectively. experimental findings compared values, they close agreement.
