Abstract Thermal conductivity and rheology behavior of two aqueous nanofluids, i.e., alumina and multi-walled carbon nanotube (MWCNT) nanofluids, were
experimentally investigated and compared with previous analytical models. Information about the possible agglomeration size and interfacial thermal
resistance in the nanofluids were obtained and partially validated. By incorporating the effects of interfacial thermal resistance, a revised model was
found to accurately reproduce the experimental data based on the agglomeration size extracted from the rheology analysis. In addition, the thermal
conductivity change of the alumina/water nanofluid with elapsed time was investigated. Thermal conductivity measurements were also conducted for
alumina/water and MWCNT/water nanofluid mixtures. More >
