Numerical Modeling of Wet Steam Flow in Steam Turbine Channel [PDF]

open access: yes, 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 ...

Toward Pore‐Engineered 3D‐Printed Materials for Sorption Water Harvesting, Interfacial Evaporation, and Radiative Cooling

open access: yesAdvanced Materials, EarlyView.
Water harvesting, radiative cooling, and interfacial solar evaporation are fundamentally governed by coupled heat, mass, and light transport processes. These processes are mediated by pore architecture, including pore size, connectivity, and hierarchical organization.

Patterned Screen‐Printing Process for Substrate‐Free and Scalable Hyaluronic Acid Microneedle Arrays

open access: yesAdvanced Materials Technologies, EarlyView.
A substrate‐free microneedle array comprising a hybrid hyaluronic acid ink was fabricated via a scalable screen‐printing process for flexible transdermal drug delivery. Defect‐free mold filling was achieved using a vacuum‐assisted jig and a delayed drying system, and the use of this versatile platform for multi‐drug patterning and ex vivo skin ...
