“…Hence, in the ballistic-diffusive regime, both the phonon boundary scattering and the phonon-phonon intrinsic scattering play an important role on the heat transfer. Furthermore, for the concentric ring geometry, previous studies [36,37] have proven that even for a given system size and temperature (T 0 , ∆ → 0), the local radial thermal conductivity is dependent of the radius in the ballistic-diffusive regime, i.e., k = k(r).…”

“…Previous work [37] based on phonon gray model shows that the radial heat transport is dominated by two parameters including the radius ratio of the two concentric boundaries (R i /R o ) and the ratio of the phonon mean free path to the characteristic length. Hence, the thermal rectification in the ballistic-diffusive regime with different characteristic length L, temperature range (T 0 , ∆) and R i /R o are investigated.…”
