Hi all.

I study physics of multiphase flows. In some cases, there are some species transfer equations with phase change . For example water evaporated in the air (The gas phase consisted of vapor +air and the Liquid phase consisted water alone) .

Suppose interface mass transfer ( water to vapor conversion) rate is known dm/ dt (on the interface). In this manner, how can I access interface boundary condition for a standard species transfer equation? Are some source terms necessary for this purpose?

Thanks a lot for any advice.
