Review of flow regime transition criteria for adiabatic co-current upward gas-liquid flow in vertical multi-scale channels

Measurement: Energy
Predicting the vertical gas-liquid flow regime in multi-scale channels is essential for optimizing system performance and design in engineering fields such as heat dissipation, petrochemical processing, and nuclear energy.

Electroosmotic Flow in Nanofluidic Channels [PDF]

Analytical Chemistry, 2014
We report the measurement of electroosmotic mobilities in nanofluidic channels with rectangular cross sections and compare our results with theory. Nanofluidic channels were milled directly into borosilicate glass between two closely spaced microchannels with a focused ion beam instrument, and the nanochannels had half-depths (h) of 27, 54, and 108 nm ...

What Drove the GICs >10 A During the 17 March 2013 Event at Mäntsälä? A Novel Framework for Distinguishing the Magnetospheric Sources

Space Weather
We combine wavelet analysis and data fusion to investigate geomagnetically induced currents (GICs) on the Mäntsälä pipeline and the associated horizontal geomagnetic field, BH, variations during the late main phase of the 17 March 2013 geomagnetic storm.

Phase Distribution of Gas–Liquid Slug–Annular Flow in Horizontal Parallel Micro-Channels

Energies
As a transitional flow pattern, slug–annular flow occurs over a wide range of operating conditions in micro-channels while its distribution in parallel micro-channels has not been well characterized.

Capillarity in lithographically patterned micro channels [PDF]

, 2013
The spontaneous capillary-driven filling of micro channels is important for a wide range of applications. Reporting for the first time for vertically mounted open top channels, in this work the theory for capillary rise in channels of rectangular cross ...

Grease flow in an elbow channel [PDF]

Tribology Letters, 2015
The flow of lubricating greases in an elbow channel has been modeled and validated with velocity profiles from flow visualizations using micro-particle image velocimetry. The elbow geometry induces a non-symmetric distribution of shear stress throughout its cross section, as well as varying shear rates through the transition from the elbow inlet to the

Transverse flow distributions in ice‐covered channels

River, 2023
Traditional discharge measurements in ice‐covered river channels are time‐consuming and costly, thus limiting the elucidation of flow patterns during winter. This study proposes an analytical model for quantifying the transverse distributions of the unit‐

The effect of melt-channel geometry on ice-shelf flow

Journal of Glaciology
Basal channels are incised troughs formed by elevated melt beneath ice shelves. Channels often coincide with shear margins, suggesting feedbacks between channel formation and shear.

Intravascular flow stimulates PKD2 (polycystin-2) channels in endothelial cells to reduce blood pressure

eLife, 2020
PKD2 (polycystin-2, TRPP1), a TRP polycystin channel, is expressed in endothelial cells (ECs), but its physiological functions in this cell type are unclear.

Gravity currents in rotating, wedge-shaped, adverse channels [PDF]

, 2014
Results are presented from a series of parametric experimental and analytical studies of the behaviour of dense gravity currents along rotating, up-sloping, wedge-shaped channels.
