Abstract
This work aims to evaluate the synthesis and characterization of nanofluids of carbon nanotubes of multiple walls (MWCNT) functionalized with -OH in distilled water. For this, the thermophysical properties of these nanofluids were measured: thermal conductivity and viscosity under various temperatures (20-50 ° C) and concentration range of 0.005 to 0.01% by volume. Increases in viscosity and conductivity of 9.3% and 4.7%, respectively, were found for volumetric concentration of 0.01% at the temperature of 30°C.
