Summary:This article presents a thermodynamic model that offers the advantage of simplifying the calculation process and effectively explaining the complex mechanism of double throttling within the ejector for real gases. The paper begins by describing the model's assumptions and the calculation procedure. It then assesses the influence of the various parameters on yields. The validity of the model is confirmed by validation using several data sets. In addition, the ejector model is applied to the simulation of an ejector refrigeration cycle in order to guarantee its reliability and its ability to predict the performance of thermodynamic cycles.
