An Experimental Study on the Thermal Conductivity of Carbon Nanotubes/Oil (TECHNICAL NOTE)
[if gte mso 9]> In the present work, the thermal conductivity coefficients of nanoparticle-oil suspensions for two types of carbon nanotubes, single-walled (SWNTs) and multi-walled (MWNTs) carbon nanotubes at 0.1, 0.2 and 0.3 wt.% were measured by a modified transient hot wire method (KD2-pro thermal property meter). Results showed that the thermal conductivity of suspension containing single-...
متن کاملHybrid nanofluid based on CuO nanoparticles and single-walled Carbon nanotubes: Optimization, thermal, and electrical properties
The purpose of this study is to use the thermal and electrical conductivities of copper oxide nanoparticles and carbon nanotubes for the preparation of high-performance nanofluids for achieving better heat transfer properties. These nanofluids consist of a water/Ethylene Glycol solution containing single-wall carbon nanotubes (SWCNTs) and copper oxide nanoparticles (CuONPs). The effects of such...
متن کاملSingle Walled Carbon Nanotube Effects on Mixed Convection heat Transfer in an Enclosure: a LBM Approach
The effects of Single Walled Carbon Nanotube (SWCNT) on mixed convection in a cavity are investigated numerically. The problem is studied for different Richardson numbers (0.1-10), volume fractions of nanotubes (0-1%), and aspect ratio of the cavity (0.5-2.5) when the Grashof number is equal to 103. The volume fraction of added nanotubes to Water as base fluid are lowers than 1% to make dilute ...

In this paper, finite element method is used to obtain thermal conductivity coefficients of single-walled carbon nanotube reinforced polypropylene. For this purpose, the two-dimensional representative volume elements are modeled. The effect of different parameters such as nanotube dispersion pattern, nanotube volume percentage in polymer matrix, interphase thickness between nanotube and surroun...
متن کاملRole of Interatomic Potentials in Simulation of Thermal Transport in Carbon Nanotubes
Interatomic potentials, which describe interactions between elements of nanosystems, are crucial in theoretical study of their physical properties. We focus on two well known empirical potentials, i.e. Tersoff's and Brenner's potentials, and compare their performance in calculation of thermal transport in carbon nanotubes. In this way, we study the temperature and diameter dependence of thermal...

THERMAL CONDUCTIVITY MEASUREMENT OF THIN FILM OF CARBON SWNT USING THE 300 TECHNIQUE Anton Nickolaevich Sidorov November 2005 We have measured the temperature-dependent thermal conductivity, K(1) of single walled carbon nanotubes from 300 K to 8 K by 3w method. K(1) exhibits linear temperature dependence in the entire temperature range. Our results are in good agreement with the results obtaine...
