Kairouani, Auteur Année de publication : 2011 Article en page(s) : pp. 1657-1667 Note générale : Génie Mécanique Langues : Anglais (eng) Mots-clés : Ejector Performance Operating regime Mathematical simulation Refrigerant Environmentally friendly Index. décimale : 621.5 Energie pneumatique. Machinerie et outils. Réfrigération Résumé : The present study describes a computer simulation model for refrigerant ejector. A one-dimensional mathematical model was developed using the equations governing the flow and thermodynamics based on the constant-area ejector flow model. The model includes effects of friction at the constant-area mixing chamber. The current model is based on the NIST-REFPROP database for refrigerants’ properties calculations. The simulated performance is compared with the available experimental data from the literature for validation. The effects of operating parameters and environment friendly refrigerants on critical entrainment ratio are studied.
