Jet Flood:
In spray regime operation flooding is brought about by excessive vapour flow, causing excessive liquid to be entrained in the vapour up the column. In froth and emulsion flows regimes operation excessive froth entrainment in the vapour up the column causes jet flooding

унос жидкости паром
Jet flooding, also called entrainment flooding, is caused by massive entrainment of liquid to the tray above.

% заброса флегмы (активная зона)
по идее, флегма (жидкость) в тарельчатой колонне стекает вниз, а пар восходит вверх. Жидкость, барбртируемая паром, пенится; пена растет в высоту, поднимается и достигает более высокой тарелки - получается, что флегма заброшена обратно на более высокую тарелку.

When the vapor flow through a tray increases, the height of froth in the downcomer draining the tray will also increase. This does not affect the foam height on the tray deck until the downcomer fills with foam. Then a further increase in vapor flow causes a noticeable increase in the foam height of the tray deck, which then increases the spray height.
When the spray height from the tray below hits the tray above, this is called the incipient flood point, or the initiation of jet flooding.
