Numerical Investigation of the Effects of Steam Nucleation on the Steam Ejectors Performance

Volume 7: Fluids and Heat Transfer, Parts A, B, C, and D, 2012
Steam ejectors are widely used in different applications such as propulsion, refrigeration, evacuation and aerospace. The fundamental numerical approach in evaluating the characteristic parameters of steam ejectors was through considering steam as a single-phase gas. But, at some regions in steam ejectors, nucleation of steam is occurred.

Optimization of Enhanced Steam-Ejector Applied to Steam Jet Refrigeration

Advanced Energy Systems, 1998
Abstract Ejectors are used for a wide range of applications. Refrigeration systems have, a long established history. Ejector refrigerators working on steam or halocarbon refrigerants provide a high level of flexibility. Ejector can also be used in solar-powered refrigeration systems and absorption-refrigeration systems ...

Operation of Steam Ejectors in Series.

1961
The purpose of this thesis is to investigate the performance, operating characteristics and stability of the vacuum system which has already been built to meet the requirement of the hypersonic wind-tunnel. For relating the operating variables of steam ejectors, a formula is derived for general use. [...]

Quality indicator of the main group of steam jet ejectors of a steam turbine

Safety and Reliability of Power Industry
The article presents an analysis of the influence of ejector characteristics and their number on the vacuum in the steam turbine condenser. An analysis of industrial test results for 12 ejector groups of various steam turbine units (STUs) was conducted. Based on this analysis, a new quantity — the ejector group quality indicator
