“…Most of the reported works on specific heat capacity use nanofluids based on metallic oxides, as it occurs with other thermophysical properties. Those heat capacity studies of Al 2 O 3 [4,7,15,1 6,18,19,24,26,27,29-32], SiO 2 [7,19,[33][34][35], CuO [20,[36][37][38][39] or TiO 2 [30,40] nanofluids should be highlighted. This is due to the fact that metallic oxides are relatively cheap and can be produced more easily than other nanoparticles which would warrant a more direct consideration for practical applications [41,42].…”

“…Even so, there are also nanofluid heat capacity reports on multi-wall carbon nanotubes [6,23,43] or metallic nanoparticles [2,7]. Regarding studied base fluids, it is a common practice to use water [6,15,19,24,29,36,37,39,44], ethylene glycol [2,7,15,27,36,38] or ethylene glycol + water mixtures [6,7,19,20,26,30,33]. They are the heat transfer mediums more widely used in industrial applications.…”

“…However, since solids typically exhibit inferior specific heat capacity than those of liquids, nanofluids are also expected to present lower heat capacities than their corresponding base fluids [29,51]. Thus, nanofluid specific heat decreases as the nanoparticle concentration rises based on existing experimental [ 4,7,19,26,29,30,33,36,37,40,43] and theoretical [52,53] results. Nevertheless, some studies [7,23,30,34,39,49] found the contrary behavior, i.e.…”

“…Barbés et al [56] studied thermal properties of CuO dispersed in water and ethylene glycol as a function of the particle volume fraction and at temperatures between 298 and 338°K. Thermal conductivities have been studied by the steady-state coaxial cylinders method, using a C80D microcalorimeter (Setaram, France) equipped with special calorimetric vessels.…”

In this paper, the last experimental results of the thermal conductivity of nanofluids have been investigated; therefore, because of the enormous numbers or some repetitions of such studies, it just tried to focus on those which had more acceptable results; however, it is not intended to present a systematic summary of the available references from the literature. All kinds of nanoparticles such as Al 2 O 3 , Fe 3 O 4 , TiO 2 , and CuO and their base fluids such as water, engine oil, glycol, and ethylene glycol have been investigated. The results showed that the effect of particle size of nanoparticle has a reversed impact on the value of thermal conductivity. To clarify, the thermal conductivity could increase by reduction in size of nanoparticles. On the other hand, the lower the suspension volume fraction is, the higher the thermal conductivity will be in nonlinear relation. Also the thermal conductivity and the temperature of the suspension have the direct influence on each other. In addition to the fact that a review paper has been prepared, the belief is to start this research with the scientific classification in order of all terms and expressions which have been used by previous scholars.

The effects of temperature and concentration on the flow behavior and viscosity of nanofluids containing TiO 2 nanoparticles, pristine MWCNTs, oxidized MWCNTs and decorated MWCNTs with TiO 2 nanoparticles are experimentally investigated. The results of rheological characteristics of nanofluids revealed that nanofluid of TiO 2 nanoparticle and MWCNT-TiO 2 exhibits shear thickening or dilatant behavior. In contrast, nanofluids containing pristine and oxidized MWCNTs depict the shear thinning or pseudoplastic behavior. Also results demonstrated that the rheological characteristics of nanofluids are functions of temperature and concentration, whereas the viscosity of all prepared nanofluids decreases with increasing the temperature and decreasing the concentration. In addition, the results show that the oxidation of MWCNTs in nitric acid leads to the reduction in viscosity. The rheological behavior of decorated MWCNTs illustrates that viscosity decreases by increasing the attached TiO 2 nanoparticles. TEM results show that TiO 2 nanoparticles successfully attached to the outer surface of oxidized MWCNTs.
