Abstract: A convergent nozzle is in a flow path from a liquid inlet of the ejector and a liquid outlet of the ejector. A convergent end of the convergent nozzle has a smaller cross-sectional area than an inlet of the convergent nozzle. The convergent nozzle is sized to increase a velocity of the liquid to supersonic velocities and decrease a pressure of the liquid. A low pressure housing includes a low pressure inlet into an interior of the low pressure housing. A convergent-divergent nozzle includes a mixed liquid inlet in fluid communication to receive fluid from the convergent nozzle and the low pressure housing.
