The objective of this work is to provide a literature survey on the research attempts made in
the field of ejector refrigeration systems and the studies made on the ejector as a …

This paper presents a useful knowledge of ejector working principles and the versatility and
diversity of its applications in refrigeration technologies. Various ejector refrigeration …

Ejector refrigeration has not been able to penetrate the market because of the low coefficient
of performance and because of the high influence of ejector performance on the efficiency of …

The efficiency of ejector-based systems (the “system-scale”) relies on the behaviour of the
ejector (the “component-scale”), related to the flow phenomena within the component itself …

The actual operating boundary conditions under different Proton Exchange Membrane Fuel
Cell (PEMFC) power outputs are considered to evaluate the performance of a confocal twin …

One-dimensional theoretical methods are always utilized for analysis of performances of a
steam ejector but they commonly have certain limitations. Numerical simulation and analysis …

Ejectors used in refrigeration systems as entrainment and compression components or
expanders, alone or in combination with other equipment devices, have gained renewed …

In this study, the cause of the boundary layer separation, the determination of the separated
region and the effect of the boundary layer separation on ejector performance were …

Ejectors can greatly improve the efficiency of proton exchange membrane fuel cells
(PEMFCs) by pumping unreacted hydrogen, and boundary layer separation (BLS) …

The present work reports a numerical analysis of a supersonic ejector in single-phase
conditions using R134a as the working fluid. A numerical benchmark of some …
