Radiative heat transfer between two carbon nanotubes [PDF]

open access: yesScientific Reports, 2022
We analyze the radiative heat transfer between two parallel and infinitely long carbon nanotubes (CNTs). The radiative heat exchange is due to the difference between the Poynting vectors generated by the fluctuating currents when the CNTs are at ...

Homogenization of a Conductive and Radiative Heat Transfer Problem [PDF]

open access: yesMultiscale Modeling and Simulation, 2009
This paper is devoted to the homogenization of a heat conductionproblem in a periodically perforated domain with a nonlinear andnonlocal boundary condition modeling radiative heat transfer inthe perforations. Because of the critical scaling considered it isessential to use a method of two-scale asymptotic expansionsinside the variational formulation of
