A comparative parametric study of two theoretical models of a single-stage, single-fluid, steam jet ejector

Effect of thermo-compression on the design and performance of falling-film multi-effect evaporator

“…This steam, produced in the thermo-compressor, is the heating medium of one effect of the evaporation system. Thermo-compressors have been modeled under different suppositions (Gupta et al, 1979). One of these considers the thermo-compressor as an isentropic system whose application requires complex algorithms to calculate the pressure of the mix (Aly et al, 1999).…”

Numerical study for the influences of primary nozzle on steam ejector performance

“…A steady solution is achieved by switching time step to a large-enough value after several temporal results were obtained. Therefore, the unsteady-state mathematical 5 model here is used for numerical simulation of the flow inside the steam ejector, which is presented as follows.…”

“…It has been widely used in many industries, such as refrigeration [1][2][3], vacuum pumps [4][5], thermal compressor [6][7] and so on for its simple structure, low running cost and little maintenance. However, despite of its simple structure, the fluid flow inside is extremely complex, including trans-sonic flow, shockwaves, irreversible mixing, phase change (condensation and re-evaporation), boundary separation, etc.…”

New steam generation system for lead-cooled fast reactors, based on steam re-circulation through ejector

“…not containing moving parts) composed by ducts able to transfer energy from a high pressure driving fluid to a driven fluid. Many authors have faced the issue of ejectors mathematical modeling, and the literature reports several examples of steam jet ejector models implementation, from the simpler [21][22][23][24] to the more complicated ones [25,26].…”
