Atomistic-mesoscale interfacial resistance based thermal analysis of carbon nanotube systems
نویسندگان
چکیده
This paper estimates the effect of chemical additives like CuO on the interfacial thermal resistance of carbon nanotubes (CNTs) embedded in water. The investigation of thermal properties of CNT nanostructure is carried out using molecular dynamics (MD) simulations. The nanotube was heated to a prescribed temperature, followed by the relaxation of the entire configuration. In the equilibration simulations, the atoms in the nanotube are heated instantaneously to 500, 750 and 1000 K in 3 separate simulations by rescaling the velocities of carbon atoms in the nanotube. This paper also deals with the mesoscale thermo-conductivity properties of the composite system, by employing various effective medium theories and micromechanical methods. © 2007 Elsevier Masson SAS.

Interfacial Thermal Resistance Between Carbon Nanotubes: Molecular Dynamics Simulations and Analytical Thermal Modeling
Interfacial thermal transport between offset parallel (10,10) single-wall carbon nanotubes is investigated by molecular dynamics simulation and analytical thermal modeling as a function of nanotube spacing, overlap, and length. A four order of magnitude reduction in interfacial thermal resistance is found as the nanotubes are brought into intimate contact. A reduction is also found for longer n...
متن کاملThe Prediction of thermal properties of single walled carbon nanotube suspensions
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 thermal conductivity of gas-permeated single-walled carbon nanotube (SWCNT) aerogel (8 kg m − 3 density, 0.0061 volume fraction) is measured experimentally and modeled using mesoscale and atomistic simulations. Despite the high thermal conductivity of isolated SWCNTs, the thermal conductivity of the evacuated aerogel is 0.025 ± 0.010 W m − 1 K − 1 at a temperature of 300 K. This very low va...

متن کاملExperimental Study on Interfacial Thermal Transport of Multi-Walled Carbon Nanotube
Interfacial thermal transport of multi-walled carbon nanotube is explored by using T-type sensor. Reliable signals of heat flow through an individual nanotube were obtained. Estimated thermal boundary resistances between the end of CNT and solid surfaces do not show the clear dependency on material that has been predicted by the diffuse mismatch model treating graphite. This discrepancy is main...
