Enhanced thermophysical properties of multiwalled carbon nanotubes based nanofluids. Part 1: Critical review Academic Article uri icon

abstract

  • © 2017 Elsevier Ltd Recently reported anomalous thermal conductivity enhancement in carbon nanotube nanofluids is in disagreement with the known physical theories for heat transfer fluids. Many researchers have modified existing theoretical models using recent experimental data to highlight the importance of certain physical mechanisms that should be prevalent at the nanoscale. In this study, available experimental data have been mapped and the discrepancies among them have been highlighted and compared using the available physical models. The proposed theories seem not capable of predicting the experimental data with reasonable accuracy. Analysis reveals that the measurement techniques used by researchers in the area of nanofluids should be standardized. In Part 2 of this study, collected experimental data indicate that the Maxwell's theory predictions can accurately be used to determine the effects of using nanoparticles on thermal conductivity.
