Dielectric properties of wet steam based on a double relaxation time model

, 2019
The last stages of most steam turbines operate in wet steam, resulting in water erosion of the rotor blades and the reduction of turbine efficiency. Accurate measurement of steam wetness is the key to ensure an efficient and stable operation of steam ...

The expansion of wet steam through a compressible confined vortex in a fluidic vortex diode

, 2003
The pressure-flow characteristics of a Zobel-type vortex diode have been measured using a working fluid of compressible wet steam. Tests using superheated steam with inlet/outlet pressure ratios across the diode of up to 30 have shown clearly the effects

ALD Derived Li2O Layer Stabilizing Solid Electrolyte Interphase of Silicon/Carbon Anodes for Lithium Storage

Carbon Energy, EarlyView.
A durable solid electrolyte interphase (SEI) is essential for mitigating the mechanical fracture and interfacial instability of silicon anodes under strong electrochemical‐mechanical coupling. Herein, a uniform Li2O layer was accurately deposited on the Si/C composites to regulate the growth characteristics of SEI.

Efficient Solar‐Driven Interfacial Steam‐Electricity Co‐Generation by Modular Design of CAU‐23/Graphene Hybrid Evaporator

Carbon Energy, EarlyView.
A dual‐functional evaporator based on CAU‐23/graphene hybrid is acquired through a modular design strategy. Owing to superior broadband light absorption, optimal wettability, and porous architecture that synergistically integrates nanoconfined ionic channels with photothermal conversion, it exhibits a high evaporation rate of 2.71 kg m−2 h−1 with the ...
