The effects of the main flow parameters on the velocity and temperature behavior are illustrated. 2015-01-26 This paper presents a brief review on the viscous and thermal transport effects of nanofluids. The main emphasis is on the comparison of previous theoretical and experimental studies for thermophysical properties of nanofluids. These properties include density, viscosity, thermal conductivity and specific heat capacity of nanofluids.

Our work has a major impact on the field of nanofluids and nanocomposites demonstrated by 20 publications 2010-05-28 Our findings demonstrated that the thermal conductivity enhancements of nanofluids could be influenced by multi-faceted factors including the volume fraction of the dispersed NPs, the tested temperature, the thermal conductivity of the base fluid, the size of the dispersed NPs, the pretreatment process, and the additives of the fluids.

To test the validity of this assumption, we have considered seven slip mechanisms that can produce a relative … 2011-12-02 technique has been developed and used to synthesize nanofluids. The thermal transport properties of nanofluids, including thermal conductivity, viscosity, heat capacity and heat transfer coefficient in convective environment were characterized and modeled. Obvious thermal conductivity increases have been observed in these nanofluid systems, e.g., 52% Nanofluids have greatly enhanced thermal properties which makes their use in thermal management.

Because convection and mass transfer are similar processes, the objective here is to visualize dye diffusion in nanofluids. It is observed that dye diffuses faster in nanofluids compared to that in Nanofluids have greatly enhanced thermal properties which makes their use in thermal management. Recent experiments on nanofluids have indicated significant increase in thermal conductivity compared with liquids without nanoparticles or larger particles, strong temperature dependence of thermal conductivity, and significant increases in critical heat flux in boiling heat transfer.
