In this paper we put forward a quantitative analysis based on the collision-mediated heat transfer model for water-based Al2O3 nanofluids, which can account for the difference in the thermal conductivity values of nanofluids obtained by LFM

• now be demonstrated that the experimentally observed differences between the conductivity values obtained by LFM and THWM can be quantitatively accounted for on the basis of the present collision-mediated heat transfer model of nanofluids. Figure 6 shows the collision frequency as a function of L for
