[Modèle analytique pour la résistance thermique due à des contacts circulaires mobiles multiples à la surface d'un solide revêtu]
Le transfert de chaleur à l'interface de deux solides en contact glissant/roulant dépend des phénomènes de constriction qui ont lieu au voisinage des aspérités. Pour étudier ce problème, les micro-contacts sont représentés par de multiples sources de chaleur circulaires mobiles à la surface du solide. Celui-ci est constitué d'un substrat et d'un revêtement. La résistance thermique de constriction due à ces contacts est déterminée analytiquement dans cet article. La solution est développée à partir des transformées intégrales de Fourier. Elle est valable quelles que soient la vitesse et la taille relative du contact.
The heat transfer at the interface of two solids in sliding/rolling contact depends on the constriction phenomenon which occurs at the vicinity of asperities. In order to study this problem, the micro-contacts are represented by multiple moving circular heat sources on the surface of a body. The studied body is constituted of a substrate and a surface coating. The thermal constriction resistance due to those contacts is determined analytically in this paper. The solution is developed by using the integral Fourier transforms, and it is valid regardless of the velocity and the relative contact size values.
