In this paper, the thermal conductivity characteristics of the alpha(2)-graphyne nanotubes are investigated. Molecular dynamics simulations are used for this purpose. The influences of chirality, diameter, length, strain and temperature on the thermal conductivity coefficient of the alpha(2)-graphyne nanotubes are explored. It is observed that the thermal conductivity coefficient of alpha(2)-graphyne nanotubes is significantly smaller than that of the carbon nanotubes. Besides, the thermal conductivity of the alpha(2)-graphyne nanotubes increases by increasing the nanotube diameter. However, longer alpha(2)-graphyne nanotubes have smaller thermal conductivity coefficients. Thermal conductivity coefficients of the armchair and zigzag alpha(2)-graphyne nanotubes are decreased by increasing the temperature.
