Evaporation at interface between liquid/gas zones
Has anyone written UDF's to simulate evaporation from porous zones similar to evaporation from the wick of a heat pipe. Basically there are 2 adjoining zones, one with a porous medium representing a wick, and another containing a gas mixture (hydrogen+water vapor). I want to write a mass transfer UDF to model mass and energy transfer between the 2 media. Is it possible to write a UDF for an internal surface in Fluent or do I need to take a different approach?
