A model has been developed to predict the effective thermal conductivity of carbon nanotube (CNT) suspensions. This model uses a set of dimensionless groups based upon the properties of the base fluid, the CNT‐fluid interface, and characteristics of the nanotubes themselves, such as diameter, aspect ratio, and thermal conductivity. According to the model, the thermal conductivity of the CNT suspension increases in a nonlinear way as the CNT concentration is increased. The model is in good agreement with experimental data that was obtained for a series of CNT–R113 (Cl 2 FC‐CClF 2 ) nanofluids.
