Advancements in Hypersaline Wastewater Treatment: The Promise of Quasi‐Liquid Surfaces to Reduce Salt Scaling

Advanced Functional Materials, EarlyView.
Durable quasi‐liquid polymer brush surfaces provide an anti‐scaling strategy for hypersaline brine evaporation and zero‐liquid‐discharge desalination. The smooth, liquid‐like QLS interface suppresses substrate‐side salt nucleation, promotes compact crystallization and dewetting, reduces crystal–surface contact area, and enables low‐adhesion salt ...

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 ...
