Web16 de fev. de 2024 · Heat conduction, being one of the most common types of energy, occurs everywhere at any time in nature. On the long journey to explore the optimal structural design for the ubiquitous heat conduction problem, many insights have been reported, yet still identifying the best structural morphogenesis remains pending and … WebWe study networks of interacting oscillators, driven at the boundary by heat baths at possibly different temperatures. A set of first elementary questions are discussed concerning the uniqueness of a stationary possibly Gibbsian density and the nature of the entropy production and the local heat currents. We also derive a Carnot efficiency relation for the …
