Bubble Pump


Bubble pumps (aka vapor-lift pumps and air-lift pumps) use generated vapor or injected gases to lift columns of liquid. They are of interest for adsorption refrigeration cycles.

This sample problem compares predictions to results from a water vapor-lift pump test program. While a validation could not be made due to lack of key data, various important two-phase modeling ideas are discussed, including slip flow.
