“…The thermal conductivity and the heat transfer of metal nanofluids suspensions are remarkably higher than conventional fluids [27][28][29][30][31][32]. Li and coworkers showed that the utilization of copper nanoparticles enhance the heat and mass transfer of the HFC134a hydrate formation process [24].…”

“…Examples for metal oxide nanofluids are given below. Behabadi et al [2] used CuO nanofluids, Naik et al [3,4], Michael and Iniyan [5], Bouhalleb and Abbassi [6] and Goudarzi et al [7] also used CuO nanofluid and obtained better heat transfer rates. Abbassi et al [8], Hemant Kumar et al [9], Shojaeizadeh et al [10] and Esfe et al [11] studied the thermal properties of Al 2 O 3 nanofluids using different experimental methods.…”

This article reports the effects of CuO/water based coolant on specific fuel consumption and exhaust emissions of four stroke single cylinder diesel engine. The CuO nanoparticles of 27 nm were used to prepare the nanofluid-based engine coolant. Three different volume concentrations (i.e 0.05%, 0.1%, and 0.2%) of CuO/water nanofluids were prepared by using two-step method. The purpose of this study is to investigate the exhaust emissions (NO x ), exhaust gas temperature and specific fuel consumption under different load conditions with CuO/water nanofluid. After a series of experiments, it was observed that the CuO/water nanofluids, even at low volume concentrations, have a significant influence on exhaust emissions. The experimental results revealed that, at full load condition, the specific fuel consumption was reduced by 8.6%, 15.1% and 21.1% for the addition of 0.05%, 0.1% and 0.2% CuO nanoparticles with water, respectively. Also, the emission tests were concluded that 881 ppm, 853 ppm and 833 ppm of NO x emissions were observed at high load with 0.05%, 0.1% and 0.2% volume concentrations of CuO/water nanofluids, respectively.

“…So, this indicates that there may be a possibility of further augmentation of heat transfer by using turbulent promoters. Nanofluids flow in a tube with different kind of inserts is also available in the literature [26][27][28][29][30][31], but they considered single-nanoparticles for the preparation of nanofluids.…”
