“…The heat transfer enhancement by nanofluid coolants is generally accompanied with the increase in pressure drop [247]. Hence, a compromise between the higher heat transfer and the associated higher pressure losses has to be considered by introducing performance indexes.…”

Engineered suspensions of nanosized particles (nanofluids) may be characterized by enhanced thermal properties. Due to the increasing need for ultrahigh performance cooling systems, nanofluids have been recently investigated as next-generation coolants for car radiators. However, the multiscale nature of nanofluids implies nontrivial relations between their design characteristics and the resulting thermo-physical properties, which are far from being fully understood. In this work, the role of fundamental heat and mass transfer mechanisms governing thermo-physical properties of nanofluids is reviewed, both from experimental and theoretical point of view. Particular focus is devoted to highlight the advantages of using nanofluids as coolants for automotive heat exchangers, and a number of design guidelines is reported for balancing thermal conductivity and viscosity enhancement in nanofluids. We hope this review may help further the translation of nanofluid technology from small-scale research laboratories to industrial application in the automotive sector.

In previous studies, few articles investigated the tribological properties of nanofluid‐lubricated ceramic specimens. Therefore, this research focused on the tribological performance of an alumina ball sliding against a steel plate lubricated with ZnO or diamond nanofluids using oleic acid as surfactant. The coefficient of friction obtained with various concentrations of ZnO and diamond nanoparticles was approximately constant at 0.08. Scanning electron microscopy (SEM) was used to explore the possible mechanisms of wear with the nanofluids. Generally, as the diamond or ZnO concentration of nanoparticles with oleic acid increases, the disk and ball wear increase. The higher concentration of nanoparticles leads to enhanced three‐body abrasive wear. Diamond nanofluids produced higher ball wear than ZnO nanofluids. The hard diamond particles likely embedded in the disk and/or acted as third‐body particles, which abraded the ball at a high rate.

Furthermore, results demonstrated that the ZnO/EG-W nanofluid might be promising alternatives for conventional coolants [30]. Chung et al researched the effectiveness of ultrasonic dispersion.…”

In this study, the thermo physical properties of the nanofluid obtained with prepared solution by adding as basic fluid 1.3% the diatomite nanoparticles into water were determined. Many researchers are working to improve the performance of heat transfer fluids. One of the methods used, if we want to increase the overall thermal conductivity of the fluid, the high thermal conductive materials such as metal oxides, metals and carbon should be added to heat transfer fluids as nano-sized particles. In this study, specific heat capacity, thermal conductivity and viscosity of nanofluid obtained with diatomite nanoparticles in order to increase the fluid's thermal performance and not found in the literature were investigated experimentally.
