Is reactingParcelFilmFoam able to treat cases of two gas-liquid interfaces?

Usually, it treats cases of one side of gas-liquid interface and the other of solid-liquid interface. But, there are many thin layer flows whose interfaces confronting only gases (cf. middle of waterfall).

Particularly, I am instrested in the flows whose one side is devided by solid-liquid interface and gas-liquid interface (cf. top of waterfall).

Is there any method to treat the above situations?

Sincerely,
