Development of a shock circle model based on the two-dimensional distribution to assess the performance of a supersonic ejector used in refregeration systems
Résumé
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.
