Review on ejector efficiencies in various ejector systems.

Number: pap. 2580

Author(s) : LIU F.


The efficiency of the ejector cycle is very sensitive to the ejector efficiency. This paper provides a literature review on ejector efficiencies in various ejector systems, such as vapor compression systems, solar driven ejector systems. The definitions of overall ejector efficiency and ejector component efficiencies in literature are summarized. The assumed constant ejector component efficiencies used in the ejector modeling, and the empirical correlations of the ejector efficiencies developed based on the external measured parameters are summarized and compared; the methods of determining energy efficiencies are summarized. The effects of ejector geometries, operating conditions and working fluid characteristics on ejector efficiencies are discussed. This review will be useful for further research on ejector efficiency, optimal design and control of ejectors and ejector systems.
