Experimental Studies of Nanofluid TiO2/CuO in a Heat Exchanger (Double Pipe)


Objectives: Nanofluid TiO2/CuO was used in a heat exchanger (double pipe) for the observation of behaviour of heat transfer with flow rate and concentration of nanoparticles at ambient temperature. Methods/Statistical Analysis: Experimental data have been generated in double pipe heat exchanger using nanofluid and Gnielinski, Duangthongsuk and Wongwises, and Petukov correlation were used for the verification of the experimental data. Findings: The results predict that CuO act as a better nanoparticle in comparison to TiO2 due to high thermo-physical properties of the mixture, yield in the increase in heat transfer. Experimental results show that application of TiO2/CuO based nanofluid enhances coefficient of heat transfer by 5 % at 0.3% concentration by volume and a flow rate of 4 LPM respectively. Experimental observations were found to be fitted and revealed better agreement with Duangthongsuk and Wongwises correlations. Application/ Improvements: The results shows that TiO2/CuO based nanofluid are useful for improvement of the thermophysical properties yield in high heat transfer of heat exchanger used in process industries.
