“…Surface tension is determined by fitting the shape of the droplet to the Young-Laplace equation which relates surface tension to droplet shape. Pantzali et al (2009) used the pendant droplet method to measure the surface tension of the CuO water-based nanofluids. The other common method to measure surface tension is the capillary method (Golubovic et al, 2009).…”

“…The nanofluid in these studies consists mainly of CuO/water [1,2], CuO/ethylene glycol [3], Al 2 O 3 /ethylene glycol [3,4], Al 2 O 3 /water [4][5][6][7][8][9], Al 2 O 3 /ethylene glycol/water [10], TiO 2 /water [8,11], and Ag/methanol nanofluid [12]. Moreover, heat exchangers used in these studies include the microchannel heat sink (MCHS) [1,7,10], miniature-plate heat exchanger [2], plate heat exchangers [3], double-tube flow heat exchanger [3,11], multichannel heat exchanger [5], shell and tube heat exchanger [8], finned tube heat exchanger [9,13], and the thermosyphon heat exchanger [12]. Results of these studies demonstrate that nanofluid could improve the performance of heat exchangers.…”

This study analyses the density and specific heat of alumina (Al 2 O 3 )/water nanofluid to determine the feasibility of relative calculations. The Al 2 O 3 /water nanofluid was produced by the directsynthesis method with cationic chitosan dispersant served as the experimental sample, and was dispersed into three concentrations of 0.5, 1.0 and 1.5 wt.%. This experiment measures the density and specific heat of nanofluid with weight fractions and sample temperatures with a liquid density meter and a differential scanning calorimeter (DSC). To assess the availability of these equations, it then compares the experimental data with the calculated results according to the concepts of mixing theory and statistical mechanism. Comparing the calculated results of density and specific heat with the experimental data, the deviation of density fell within the range of À1.50% to 0.06% and 0.25% to 2.53%, whereas the deviation of specific heat fell within the range of À0.07% to 5.88% and À0.35% to 4.94%, respectively. Calculated results of density and specific heat show a trend of greater deviation with an increased concentration of nanofluid. However, two kinds of density and specific heat of the calculated results fall within an acceptable deviation range in this study.

This paper presents results of investigations on the application of CuO-water nanofluids for intensification of convective heat transfer. Performance of nanofluids with 2.2 and 4.0 vol.% CuO NPs (nanoparticles) content were examined with regard to heat transfer coefficient and pressure losses in case of turbulent flow in a tube. Negligible impact of examined nanofluid on heat transfer improvement was found. Moreover, measured pressure losses significantly exceeded those determined for primary base liquid. The observations showed that application of nanofluid for heat transfer intensification with a relatively high solid load in the examined flow range is rather controversial.
