“…Researchers have done multiple studies with this topic and have concluded that a higher temperature associates with higher thermal conductivity of nanofluids. The nanofluids have shown that they are more temperature dependent than their base fluids suggesting that the observed increase in thermal conductivity is not just simply explained by the increase in the thermal conductivity of the base fluid [ 1 ]. Kwek et al [ 24 ] performed measurements on the effect of temperature on thermal conductivity on Al 2 O 3 –water nanofluids.…”

“…Initially, attempts were made to increase the thermal properties of working fluids with the millimeter and micrometer sized particles. These fluids had many problems though such as clogging of fluid paths, abrasion, and pressure drop [ 1 ]. In an effort to create a working fluid without these problems in 1995, Choi [ 2 ] first added nanoparticles to working fluids to create a nanofluid.…”

This review was focused on expressing the effects of base liquid, temperature, possible surfactant, concentration and characteristics of nanoparticles including size, shape and material on thermal conductivity and viscosity of nanofluids. An increase in nanoparticle concentration can lead to an increase in thermal conductivity and viscosity and an increase in nanoparticle size, can increase or decrease thermal conductivity, while an increase in nanoparticle size decreases the viscosity of the nanofluid. The addition of surfactants at low concentrations can increase thermal conductivity, but at high concentrations, surfactants help to reduce thermal conductivity of the nanofluid. The addition of surfactants can decrease the nanofluid viscosity. Increasing the temperature, increased the thermal conductivity of a nanofluid, while decreasing its viscosity. Additionally, the effects of material of nanoparticles on the thermal conductivity and viscosity of a nanofluid need further investigations. In the case of hybrid nanofluids, it was observed that nanofluids with two different particles have the same trend of behavior as nanofluids with single particles in the regard to changes in temperature and concentration. Additionally, the level of accuracy of existing theoretical models for thermal conductivity and viscosity of nanofluids was examined.
