“…Enhancement in overall heat transfer coefficient was 23.9% at ϕ v = 0.5% and base fluid-flow rate of 90 ph and Sonawane [11] concluded that Gnielinski correlation provides more accurate results as compared to both Dittus-Boelter and Xuan and Li correlation. Therefore, in the current study, Gnielinski correlation for turbulent flow, given by eq.…”

“…The highest improvement in convective heat transfer coefficient was 14.29%, 12.89%, 10.10%, 9.86%, 9.76%, and 2.18% for Al 2 O 3 , Fe 3 O 4 , TiO 2 , ZnO, CuO, and SiO 2 nanofluids, respectively, at a volume concentration of 0.3% and a mass-flow rate of 50 kg per minute for both shell side and tube side fluid. Kumar and Sonawane [11] experimentally measured the heat transfer performance of nanofluids, prepared by suspending Fe 2 O 3 nanoparticles in two types of base fluids i. e. water and ethylene glycol. They observed a 20% improvement in the convective heat transfer coefficient for Fe 2 O 3 -water nanofluids and 13% for Fe 2 O 3 -EG nanofluids.…”

Original scientific paper https://doi.org/10.2298/TSCI180615291SThermal-hydraulic characteristics of water based ZrO 2 nanofluids has been investigated in a segmental baffled shell and tube heat exchanger in turbulent flow regime. The effect of Reynolds number, nanoparticle loading, mass-flow rate, and tube lay-out has been analysed on overall heat transfer coefficient. The effect of Reynolds number on the tube side pressure drop and convective heat coefficient have also been discussed. The effect of shell side mass-flow rate was also investigated on shell side heat transfer coefficient determined using Bell-Delaware method. The nanoparticle volume concentration is taken very low i. e. 0.2%, 0.4%, and 0.8%, respectively. The improvement in both tube side convective heat transfer coefficient and overall heat transfer coefficient has been observed. The maximum improvement in the convective heat transfer coefficient is found to be 14.1% for 0.8% ZrO 2 nanofluids. However, the percentage enhancement in tube side pressure drop was higher than the percentage increment in the tube side heat transfer coefficient.

“…The results showed that, using graphene oxide Nano fluids, as the hot fluid resulted in less energy loss in the shell-and-tube heat exchanger, under both laminar and turbulent conditions. Azher M. Abed, et al [5], concluded from their experiments that, the heat and mass transfer process, on falling film flow and contradictions of thermal physical properties of Nano fluids, should all be taken into careful consideration. In addition, existing research on both heat and mass transfer, regarding Nano fluids are found to be inadequate, and still requires extensive experimental and theoretical work, on their salient parameters.…”

Heat transfer rate of TiO 2 and water Nano fluids were measured in a shell and tube heat exchanger under the turbulent flow condition. Even with insignificant focus of Nano particles in the base fluids, results in enhancement of heat transfer coefficient. Heat transfer rate of TiO 2, at its optimum Nano particle concentration are greater than the water particle. From the past research, it is evident that, the addition of Nano particles increases the heat transfer rate.So for the present study, TiO 2 Nanoparticles were chosen for dispersing them in the water, for enhancing heat transfer properties and comparing them with only pure base fluid. The current study is also extended to find the overall heat transfer coefficient and the amount of heat transfer enhancement at different flow rates. Further, heat transfer characteristics like Reynolds number and effectiveness were also measured. From the experimental outcomes, it is observed that, there is a clear enhancement in the heat transfer characteristics with addition of Nano particle, at different volume concentrations (0.05%, 0.1%, 0.15% and 0.2%), for different flow rates.
