“…Owing to the advanced enhancements on thermophysical property, transport property and heat transfer potentials in many industrial applications [1][2][3][4][5], nanofluids, first proposed by a research group in Argonne National Laboratory in the USA in 1995 [6], have attracted significant interest. A nanofluid is a uniform and stable suspension, composed of nanoparticles and base fluid.…”

Abstract:In this paper, an aqueous solution of xanthan gum (XG) at a weight fraction as high as 0.2% was elected as the non-Newtonian base liquid, the multi-walled carbon nanotubes (MWCNTs) dispersed into non-Newtonian XG aqueous at different weight factions of MWCNTs was prepared. Convection heat transfer of non-Newtonian nanofluids in the shell side of helical baffled heat exchanger combined with elliptic tubes has been investigated experimentally and numerically using single-phase flow model. Results showed that the enhancement of the convective heat transfer coefficient increases with an increase in the Reynolds number and the nanoparticle concentration. For nanofluids with 0.2 wt %, 0.5 wt % and 1.0 wt % MWCNTs, the Nusselt number, respectively, increases by 11%, 21% and 35% on average at the same Reynolds number, while the comprehensive thermal performance factors are 3%-5%, 15%-17% and 24%-26% higher than that of base fluid at the same volume rate. A remarkable heat transfer enhancement can be obtained by adding MWCNTs into XG aqueous solution based on thermal resistance analysis. Correlations have been suggested for the shell-side Nusselt number and friction factor of non-Newtonian nanofluids in the helical baffled heat exchanger with elliptic tubes. Good agreements existed between corrections and experimental data.

“…Solar cells, solar thermal collectors, concentrated solar power and concentrated photovoltaic/thermal (CPV/T) can be used to convert solar energy into useful form of energy. The hybrid PV/T collector is more efficient than stand-along PV or thermal systems [3] because it can be designed to utilize nearly 80% of the incoming solar energy [4]. The hybrid PV/T collector is a sustainable technology [5].…”

“…Similar studies in this field were conducted by other researchers. [16][17][18][19] In particular, Kasaeian et al, 20 Kim et al, 21 Leong et al, 22 Mahian et al, 23 and Sarsam et al 24 presented results of very extensive work on the use of nanofluids in solar energy systems. Other potential applications for nanofluids include friction reduction, [25][26][27] magnetic sealing, [28][29][30][31] biomedical applications, 32,33 electronic cooling, [34][35][36] and many others.…”

This paper presents the results of experimental investigation of the dielectric properties of ethylene glycol (EG) with various load of boron nitride (BN) nanoparticles. The nanofuids were prepared by using a two-step method on the basis of commercially available BN nanoparticles. The measurements were carried out using the Concept 80 System (NOVOCONTROL Technologies GmbH & Co. KG, Montabaur, Germany) in a frequency range from 10 Hz to 10 MHz and temperatures from 278.15 K to 328.15 K. The frequency-dependent real (e 0 ) and imaginary (e 00 ) parts of the complex permittivity (e Ã ) and the alternating current (AC) conductivity are presented. Also, the effect of temperature and mass concentrations on the dielectric properties of BN-EG nanofluids are demonstrated. The results show that the most significant increase can be achieved for 20 wt.% of BN nanoparticles at 283.15 K and 288.15 K, that is eleven times larger than in the case of pure EG.
