A comprehensive validation of CFD-based wet steam approach for the modelling of steam ejectors
, 2023 Ejector-based system performance is closely related to the complex fluid-dynamic behavior inside ejectors, which is usually optimized through CFD simulations. The rapid expansion in ejector’s primary nozzle leads to the condensation of the working fluid,

Effect of mixing on the performance of wet steam ejectors
, 2015 Steam ejector computational simulations using a wet steam model give higher entrainment ratios and higher critical back pressures for the ejector compared with the ideal gas model. This paper identifies the origin of these differences. Simulation results

Paper 3: Nuclear Wet-Steam Turbines
, 1968 Turbines which operate on steam initially slightly wet are required by several varieties of nuclear reactor at present in service. Such turbines differ substantially from conventional fossil-fuel turbines and special measures are necessary to avoid ...

Advanced Functional Materials, EarlyView.Controlled carbonization of an Al‐MOF partially decomposes its linkers, exposing coordinatively unsaturated Al centers within an oxide/carbon composite. The resulting Lewis acid sites, rather than surface area, govern organochlorine capture: the composite removes chemically diverse organochlorines from waste plastic pyrolysis oil, outperforms a ...

Bio‐Inspired Multifunctional Superhydrophilic Coatings With Remarkably Fast Self‐Healing Abilities
Advanced Functional Materials, EarlyView.We developed bio‐inspired multifunctional hydrogel‐based coatings that exhibit extremely fast/repeatable self‐healing abilities, long‐lasting anti‐fogging performance, superhydrophilicity in air, and underwater superoleophobicity. By doping multivalent metal‐ions into the hydrogel networks, which promoted hydrogen bonding formation and enhanced the ...

Calibration of flowmeters in superheated and wet steam
, 2003 The vapour mass fraction (dryness fraction) of wet-steam flows such as those encountered in the steam main of a power or process plant will rarely be less than 90.

Enhancing Plasma Torch Efficiency: Wet Steam Cooling [PDF]
The efficient use of wet steam for plasma torch cooling and water plasma generation is important for reliable plasma generator design. Wet steam, due to phase transformation capability, improves heat removal at lower gas flow rates if compared to liquid ...

Numerical Modeling of Wet Steam Flow in Steam Turbine Channel [PDF]
, 2012 Dans la pratique des centrales électriques, le travail est extrait de la vapeur en expansion en trois étapes, à savoir les turbines à haute pression(HP), à pression intermédiaire (IP) et à basse pression(LP). Au cours du processus de détente dans la turbine BP, la vapeur se refroidit et, à certains stades, elle nucléate pour devenir un mélange ...
