However, they can be used for a great number of other pumping situations.
They often are used to pump gases and vapours from a system to create a vacuum.

Experimental investigation of a novel steam ejector refrigerator suitable for solar energy applications. In this Paper, a new approach for controlling microstructure development during hot working process by percentage of volume fraction recrystallization is proposed. One of the approaches is based on the Optimal Control theory and involves the developing of state space models to describe the material behavior and the mechanics of the process. The elemental composition of synthesized sample was confirmed by EDS analysis.
