Abstract
In this work, a new approach to estimate heat transfer coefficients for solid-gas interfaces is proposed. The new formulation takes into account that the photon transfer process between solid walls and gases is not instantaneous, but involves electronic transitions, even when low frequency radiation is exchanged. The delay required to electron cloud transitions, called relaxation time, which plays a crucial role in the heat transfer process, is evaluated using the Landau-Teller model.
