Heat transfer of a single wall carbon nanotube
Shelley, Robert A.
Master of Science
A non equilibrium molecular dynamics simulation was used to calculate thermal conductivity of a single-walled carbon nanotube (SWNT). Effective thermal conductivity was calculated for the same SWNT surrounded by nitrogen at 250K and 290K at 8 bar. Heat flux was created by implementing Nose-Hoover thermostats at the ends of the SWNT. Using Fourier's Law thermal conductivity was calculated. For both simulations thermal conductivity increased when the temperature difference between the two ends was small. As the temperature difference increased the thermal conductivity reached a constant value of around 160 W/mK in a vacuum with end temperatures close to 330K or 310 K.
