... inertia is neglected as the heat flux is not very high. The heat flux in carbon nanotubes (CNTs) may be as high as 10 12 W/m 2 . In this case, Fourier’s law no longer holds. However, what is estimated through the ratio of the heat flux to the temperature gradient by molecular dynamics (MD) simulations...
