This investigation determines carbon nanotube thermal conductivity at heat flux ranging from 0.01 to 0.3 subject to different thermal loading of 5 ∼ 50 K/nm, using a non-equilibrium molecular dynamics simulation with true carbon potentials. The numerical model adopts Morse bending, a harmonic cosine and a torsion potential. The applied Nose´-Hoover thermostate describes atomic interactions taking place between the atoms. Hot and cold temperature reservoirs are respectively imposed on both computational domain sides to establish the temperature gradient along the carbon nanotube. Atoms at the interface exhibit transient behavior and undergo an exponential type decay with exerted temperature gradient. The thermal impact causes system fluctuation in the initial 3 ps leading to a transport region temperature as high as 600K. The thermal relaxation process reduces impact energy influence after 30 ps and leads to Maxwell’s distribution. Steady-state constant heat flux is observed after thermal equilibrium. Furthermore, the temperature curves show distinct high disturbance at initial time and linear distribution along the tube axial direction after steady-state. Results suggest that thermal conductivity value increases with increasing CNT subjected to thermal loading up to a temperature gradient of at least ∼ 41.3 K/Å representing thermal gradient convergence at heat conduction value 1258. Simulation results yield precise understanding of nano-scale transient heat transfer characteristics in a single-wall carbon nanotube.
