A model for thermal conductivity of nanofluids

A survey of practical equations for prediction of effective thermal conductivity of spherical-particle nanofluids

“…In a different approach, Meibodi et al [101] claimed that the key mechanism responsible for enhanced thermal conductivity of nanofluids is the reduced distances between particles compared to corresponding distances in micro-suspensions. They proposed a new equation for thermal conductivity of nanofluids based on the mean free path of the particles.…”

A Review of Thermal Conductivity Models for Nanofluids

“…The significant features of the proposed model were summarized as follows: Emami-Meibodi et al [46,47] offered a simple new model in order to count the Brownian motion. The particle size did not involve in their model; therefore, they mentioned that their model could work for any suspension including microparticles and nanoparticles.…”

Nanofluids for Heat Transfer

“…By creating paths of low thermal resistance, clustering of particles into local percolating patterns may have a major effect on the effective thermal conductivity (Emami-Meibodi et al, 2010;Evans et al, 2008;Keblinski et al, 2002). Moreover if one takes into account the possibility of an ordered liquid layer in the immediate vicinity of the particle, it can allow a rapid and efficient transfer of thermal energy from one particle to another without any direct contact, avoiding thus large clusters and the settling.…”
