“…It could be observed that when mass fraction of DBSA-doped PANI nanoparticles was increased, the thermal conductivity of nanofluids increased. The increase was possibly related to the Brownian motion of nanoparticle [23,30]. It was reported that the Brownian motion effect of nanoparticles on thermal conductivity was more pronounced at low mass fraction of nanoparticles [31].…”

Nanofluid has attracted great attention due to its superior thermal properties. In this study, chemical oxidative polymerization of aniline was carried out in the presence of dodecylbenzenesulfonic acid (DBSA) as a dopant. Particles of DBSA-doped polyaniline (DBSA-doped PANI) with the size range of 15 to 50 nm were obtained, as indicated by transmission electron microscope (TEM). Results of ultra violet-visible (UV-Vis) absorption and Fourier transform infrared (FTIR) spectroscopies as well as thermogravimetric analysis showed that PANI nanoparticles were doped with DBSA molecules. The doping level found was 36.8%, as calculated from elemental analysis data. Thermal conductivity of water was enhanced by 5.4% when dispersed with 1.0 wt% of DBSA-PANI nanoparticles. Specific heat capacity of water-based nanofluids decreased with increasing amount of DBSA-PANI nanoparticles.

“…K Brownian = (ϕC N V N l)/3 (10) where C N is the heat capacity per unit volume of the nanoparticles, 'l' the mean free path, V N the root mean square velocity of the particles and ϕ is the volume fraction [48]. If the temperature increases the root mean square velocity increases and hence Brownian motion of dispersed NPs increases in base liquid, this increases the thermal conductivity of nanofluids [27].…”

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.
