Abstract
We consider the mixture of a light monocomponent oil and a paraffin, assuming that the latter can be dissolved in the oil or can be present in form of a crystalline phase. We study the case where a prescribed temperature gradient drives the diffusive migration of the dissolved paraffin accompar ined by the process of crystallization/dissolution. We consider the case in which a gel can be formed and present a mathematical model to take this phenomenon into account. The paper also contains some qualitative results and numerical simulation.
