The Nusselt number, total heat transfer, and convective heat transfer coefficients of glycerol-water-based Cu nanofluids operating in a parallel flow double pipe heat exchanger are calculated using CFD analysis. A single-phase fluid approach method is used in the study. The Ansys 19.0 workbench was used to develop the heat exchanger model. Heat transfer tests with nanofluids at three flow rates (680 water had mass flow rates of 0.2, 0.017, and 0.0085 kg/s in the tube, whilst nanofluids have mass flow rates of 0.03, 0.0255, and 0.017 kg/s in the annulus) were conducted in a laminar developing flow zone. The average temperature of nanofluids is 36°C, while the average temperature of hot water is 58°C. In comparison to base liquid, the overall heat transfer coefficient and convective HTC of 1.0 percent copper nanofluids at 0.03 kg/s are raised by 26.2 and 46.2 percent, respectively. When the experimental and CFD findings are compared, they are found to be quite comparable.
