Abstract
In this paper, the molecular dynamics simulations are used to compute the thermal conductivity coefficient of the strained concentric multi walled carbon and boron-nitride nanotubes. The influences of different parameters, such as nanotube diameter, length, strain, temperature and number of walls on the thermal behavior are evaluated. It is shown that the length and diameter have an increasing effect on the thermal conductivity coefficient of the concentric multi walled carbon and boron-nitride nanotubes. Similarly, the thermal conductivity of the strained nanotubes is larger than the unstrained ones. However, increasing the temperature results in decreasing the thermal conductivity coefficient of the considered nanotubes. The influence of the temperature on the thermal conductivity coefficient of the zigzag nanotube is less significant than the armchair ones.
