Quantitative criteria for identifying main flow channels in complex porous media
Petroleum Exploration and Development, 2019 To identify the type of main flow channels of complex porous media in oil and gas reservoirs, the “main flow channel index” is defined as the ratio of comprehensive permeability obtained from well test to matrix permeability obtained from core analysis ...

Frontiers in Astronomy and Space Sciences, 2021 Flow bursts are a major component of transport within the plasma sheet and auroral oval (where they are referred to as flow channels), and lead to a variety of geomagnetic disturbances as they approach the inner plasma sheet (equatorward portion of the ...

Frontiers in Astronomy and Space Sciences, 2023 Dynamic mesoscale flow structures move across the open field line regions of the polar caps and then enter the nightside plasma sheet where they can cause important space weather disturbances, such as streamers, substorms, and omega bands.

Frontiers in Astronomy and Space Sciences, 2021 We use simultaneous auroral imaging, radar flows, and total electron content (TEC) measurements over Alaska to examine whether there is a direct connection of large-scale traveling ionospheric disturbances (LSTIDs) to auroral streamers and associated ...

Flow pattern recognition in corrugated channels between circular plates
Measurement: Sensors, 2021 The path of the fluids in corrugated channels between circular plates is an arc of varying length, i.e. the flow direction firstly disperses and then converges. However, there is a shortage of data on the flow structures in these channels. In the present
