One-dimensional ejector analyses often use coefficients derived from experimental data for
a set of operating conditions with limited functionality. In this study, several ejector designs …

This paper presents an ejector model to determine the optimum performance as well as
obtaining the design area ratio of an ejector in a refrigeration system. Working fluid …

In the present paper, the numerical results for two 1 kW cooling capacity ejectors with
variable primary nozzle geometry are presented using R152a and R600a as working fluids …

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 …

A 1-D analysis for the prediction of ejector performance at critical-mode operation is carried
out in the present study. Constant-pressure mixing is assumed to occur inside the constant …

A detailed investigation of ejector working characteristics in terms of refrigeration efficiency,
ejector entrainment ratio, and irreversibilities in each ejector component (nozzle, mixing …

When an ejector is operated at choking-mode, it gives a better performance with higher
entrainment ratio. To obtain this better performance at different operating conditions, area …

The occurrence of flow choking in an ejector of an ejector refrigeration system (ERS) was
analysed and a model for predicting the maximum flow ratio of the ejector was developed …

This paper proposes a new 1D model to predict ejector performance at critical and sub-
critical operational modes, while most previous 1D models have only predicted ejector …

In the present study, two empirical correlations from the test results of 15 ejectors are derived
for the performance prediction of ejectors using R141b as the working fluid. The ratio of the …
