Résumé

Widespread research of single phase injectors has led to the development of more efficient refrigeration cycles that utilize the pressure rise induced by injectors without the input of work. The current work presented here focuses on the application of a two-phase condensing injector in a refrigeration cycle to produce a more efficient cycle. A thermodynamic investigation shows the application and limitations of a condensing injector in a two loop refrigeration cycle. The flow through a condensing injector is modeled using semi-empirical method based on an Eulerian pseudo-fluid approach using a modified form of the Homogenous Relaxation Model (HRM) implemented within the framework of OpenFOAM. The predictions are found to be metastable, in that a solution is highly dependent on inlet conditions.
