| Abstract | In a recent Letter, Kumar et al. [1] introduced a model for heat conduction in nanofluids (liquid suspensions of nanosized particles) that was capable of describing experimental results on thermal conductivity of nanofluids. The model was built in two steps. In the first step, a static problem (immobile particles) was considered in which the total heat flux was a sum of heat conduction by the liquid and particles. In the second step, the effective thermal conductivity of nanoparticles was calculated in terms of their Brownian motion and the kinetic theory of heat flow. The authors claimed that the resulting formula for the thermal conductivity, using parameters consistent with reasonable physical assumptions, quantitatively described the experimental data. |
