Interfacial heat and mass transfers

Abstract

This chapter is a short introduction to the modeling of the interfacial heat and mass transfers. First of all, we derive an approximate relation between the interfacial transfer of mass and the two interfacial heat transfers between the two phases and the interface. This approximate relation is used in numerous studies on vapor-liquid flows and we show what approximations must be done to obtain it. After then, the liquid-to-interface heat transfer is modelled in the case of bubbly flows. The two cases of conductive and convective heat transfers are clearly separated. The chapter ends with a brief presentation of the modeling of the vapor-to-interface heat transfer in the case of droplet flows.
