We report in this communication thermal conductivity measurement of carbon nanotubes water-based nanofluids. We consider in particular the influence of nanoparticle volume fraction, temperature, carbon nanotube aspect ratio and different kind of surfactant (SDBS, Lignin, Sodium Polycarboxylate) on thermal conductivity enhancement of nanofluids. In addition, various theoretical thermal conductivity models are presented in an attempt to correlate the experimental data.
