An ejector, or jet pump, is a device that uses a high pressure fluid to pump a low-pressure fluid to a higher pressure at a diffuser outlet. Due to their low cost and absent of moving parts, ejectors have been used in various engineering applications. A well-known application is the use of the ejector in refrigeration systems as a compressor to compress the refrigerant vapor from the evaporator to the condenser. This type of application is explained in [1]. However, in addition to serving as a compressor, Kornhauser [2] proposed the use of the ejector as an expansion device to expand the high-pressure refrigerant from the condenser to reach evaporator pressure.
