Multi-scale performance evaluation of ejector refrigeration systems

Despite the many advantages, ejector refrigeration systems have not been able to penetrate market because of two prevailing reasons: low coefficient performance and relevant influence operation on whole system. Indeed, depends local flow phenomena occurring within ejector. Thus, improving relies understanding fluid dynamic at "component-scale" integrating such information "system-scale". This paper contributes present discussion regarding multi-scale modeling ejector-based by proposing an integrated Computational Fluid Dynamic (CFD) - Lumped Parameter Model (LPM) In particular, performances obtained a validated CFD approach, whereas LPM approach has modeled cycle. The system's performances, for different boundary conditions, evaluated, effects "local-scale" "system-scale" commented.
