| Abstract: | Many investigations have suggested that the heat transfer coefficient at the interface between two dissimilar solids depends on the direction of heat flow across the interface. Although many factors that affect heat transfer across the interface are reasonably well understood, the directional dependence of the heat transfer coefficient, called thermal rectification, has not yet been completely explained. In this paper, we evaluate the thermal rectification from the results of linear response theory by considering scattering and transmission of phonons across the interface, which expresses the dependence of the temperature at the interface. This model explains the reported behavior of thermal rectification. © 2001 Scripta Technica, Heat Trans Asian Res, 30(2):164–173, 2001 |
