The present work is a systematic numerical study of the thermal properties of single-walled carbon nanotubes (SWNTs) in suspensions. A computational model, based on the simulation of the random movement of Brownian thermal walkers in aqueous and in oil suspensions of SWNTs, was used to investigate the effect of the SWNT aspect ratio, weight fraction, and interfacial thermal resistance on effective thermal properties of the suspension. The dependence of the effective thermal conductivity on the temperature for aqueous suspensions was also investigated.
