文摘

In this paper, thermal conductivity and rheological properties of CNT water-based nanofluids were experimentally measured, whereas density and heat capacity were evaluated from appropriate theoretical correlations. The influence of nanoparticle content and base fluids on thermophysical properties of nanofluids was presented and discussed. Then, the thermal performance and convective heat transfer of such nanofluids were investigated in a coaxial heat exchanger working in co-current flow. Fixed wall temperature boundary condition and laminar regime were also considered during the experiments. The results were presented discussing the effect of the entrance region, Reynolds number and nanofluids composition.
