The Prediction of thermal properties of single walled carbon nanotube suspensions

چکیده

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 of the interfacial thermal resistance on the suspension effective thermal properties. The dependence of the effective thermal conductivity on the temperature for aqueous suspensions was also investigated.
