Analysis of Entrainment Ratio about Solar Ejector Refrigerant System [PDF]

open access: yes, 2012
Based on the VB program, establish a simulation program about the solar ejector system performance. The characteristic of entrainment ratio has been analyzed when the HFC134a, R290 and R718 are adopted as working fluid respectively.

Experimental investigation of entrainment ratio in the near exit region of jets [PDF]

open access: yes, 2011
The behavior of volcanic ash plumes is highly dependent on entrainment ratio, which is a ratio of the radial mass inflow of air into a jet to its axial mass flow.

Mixing layer effects on the entrainment ratio in steam ejectors through ideal gas computational simulations

open access: yes, 2016
Ejector entrainment ratios are influenced by both pressure-driven effects and the mixing between the primary and secondary streams, but the significance of each factor has not been identified in prior literature.
