In order to understand the effects of particle heat transport and coagulation of particles on thermal conductivity of nanofluids, simulations were performed for Cu(100 nm)/DIW nanofluids by neglecting two-way temperature coupling (q 2w) and van der Waals interaction force (F Vi) one at a time. Nanofluids can be of two kinds such as metallic nanofluids and nonmetallic nanofluids .Metallic nanofluids are prepared by dispersing nanoparticle made from metals such as aluminum ,copper, nickel etc. and non metallic nanoparticles are made by dispersing nanoparticles of non metals i.e. metal oxides, various allotropes of carbon (Graphene, CNT)etc.

Furthermore, the link between nanoscale energy transport and bulk properties of nanofluids is not fully established. Using molecular dynamics simulations, an analysis of the thermal conductivity enhancement of a copper/argon nanofluid is performed. First, verification of an increase of as much as ∼30% in the thermal conductivity of the theoretical nanofluid over the corresponding base fluid, due to increasing nanoparticle concentration, is presented. The thermal transport mechanisms in nanofluids were further discussed, and the promising approaches for optimizing the thermal conductivity of nanofluids have been proposed.

The goals of this dissertation were (i) to investigate the mechanisms behind the thermal conductivity enhancement of nanofluids; (ii) to develop new combined mechanisms based on the analytical thermal conductivity model; (iii) to numerically investigate the fluid dynamics and heat transfer characteristics of nanofluids in a circular tube corresponding to the new analytical thermal conductivity

2.1. Effective thermal conductivity of nanofluid Jang and Choi's heat transport theory 26 is adopted to describe the effective thermal conductivity of nanofluids, k eff.Jang and Choi assumed that the Reynolds number, Re, for nanoparticles is greater than unity and the Prandtl number, Pr, is approximately 10.

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.

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% enhancement in thermal conductivity was found in water-in-FC72 nanofluids.
