Abstract
The problem of heat transfer in the system of two solids being in thermal contact is considered within the framework of the acoustic-mismatch model. It is shown that the temperature jump at the contact is responsible for the heat flux rectification effect. The model proposed is compared with the experimental results of the investigation of the heat flux rectification in the dielectric–dielectric and metal–metal systems. Das Problem der Warmeubertragung in einem System zweier Festkorper, die in thermischem Kontakt stehen, wird im Rahmen des akustischen Fehlanpassungsmodells untersucht. Es wird gezeigt, das der Temperatursprung am Kontakt verantwortlich fur den WSirmeflusgleichrich-tungs-Effekt ist. Das vorgeschlagene Modell wird mit experimentellen Ergebnissen der Warmeflus-gleichrichtung in den Systemen Dielektrikum–Dielektrikum und Metall–Metall verglichen.
