Summary

In this investigation into vapour transport across gas-filled enclosures, I first consider the various models used by earlier researchers and then construct one general enough to include all the essential physics but simple enough to be tractable. Solutions are found for simple geometries and limiting cases in order to quantify the effects of various phenomena. Here three phenomena are selected for particular attention: the interfacial velocity due to mass transfer, the interdiffusion enthalpy flux, and the role of the impermeable bounding walls connecting the source and the sink.
