Species diffusion driven mass transfer can be implemented in Fluent using Interphase species mass transfer option. In that case, the mass transfer will solely occur due to concentration gradients. nI was mentioning Thermal Phase Change in Fluent which can be used as an alternative to Lee Model when using evaporation/condensation. But yes, the mass transfer mechanism is dependent on heat exchange across the interface for this case.nI think you will need Species Mass Transfer instead. Please have a look at this link :,nSDn
