摘要：

The enhancement of the thermal conductivity of various heat transfer liquids, such as water, ethylene glycol and vacuum oil, in the presence of nanoparticles and carbon multiwalled nanotubes (C-MWNT) has been investigated. The nanoparticles employed were copper nanospheres and nanodiamonds. Sodium dodecyl sulfate (SDS), thioglycolic acid (TGA), and Triton X-100 were used as dispersants. The thermal conductivity was measured with a transient hot-wire instrument built for this purpose, and operated with a standard uncertainty better than 2%. The maximum thermal conductivity enhancement obtained was 38%, for a 0.6% vol. suspension of C-MWNT in water with 0.1% wt. SDS. All measurements were made at ambient temperature.
