Prediction model of fluctuation frequencies induced by continuity waves in slug flow

You-qi chuyun
[Objective] Slug flow is one of the main gas-liquid two-phase flow regimes. Its fluctuation characteristics not only impact the safe operation of multi-phase pumps and the measurement accuracy of multi-phase flowmeters but also arouse flow-induced ...

Numerical simulation of two-phase separation in T-junction with experimental validation

Journal of Mechanical Engineering and Sciences, 2018
Liquid carryover in T-junction due to splitting nature of two-phase flow causes serious issues for downstream equipment which is not designed to handle excessive liquid. In this paper, the phenomena of liquid carryover in T-junctions were analyzed using

Low‐Power Control Of Resistance Switching Transitions in First‐Order Memristors

Advanced Electronic Materials, EarlyView.
Joule losses are a serious concern in modern integrated circuit design. In this regard, minimizing the energy necessary for programming memristors should be handled with care. This manuscript presents an optimal control framework, allowing to derive energy‐efficient programming voltage protocols for resistance switching devices. Following this approach,

Ferroionic Electrostatic Landscapes Enabling Wireless Energy Harvesting, Storage, and Sensing

Advanced Electronic Materials, EarlyView.
By integrating experiments and electrostatic field simulations, we show that long‐range wireless coupling in Li‐based ferroionics devices emerges from the cooperative interaction between ionic migration and electronic polarization. This coupling sustains self‐polarized electrostatic fields across centimeter‐scale air gaps without external bias or ...

Competing Charge Separation Pathways Govern Charge Generation in Organic Photovoltaic Blends: Insights From Transient Electron Spin Resonance

Advanced Energy Materials, EarlyView.
Transient electron spin resonance distinguishes interfacial charge‐transfer states from separated charges, revealing competing charge separation pathways in organic photovoltaic blends. The relative contributions of fast charge separation and a pathway mediated by spin‐polarized charge‐transfer states vary across different blends, with high‐efficiency ...

Insights From Unsteady Flow Analysis of Underdamped Slug Tests in Fractured Rock

Water Resources Research, 2018
Slug tests generating oscillating (underdamped) responses are common in high‐transmissivity (T) zones, and the nature of the response depends on the plumbing of the test equipment and the formation properties.
