Flow Field Modulation

IEEE Transactions on Visualization and Computer Graphics, 2013
The nonlinear and nonstationary nature of Navier-Stokes equations produces fluid flows that can be noticeably different in appearance with subtle changes. In this paper, we introduce a method that can analyze the intrinsic multiscale features of flow fields from a decomposition point of view, by using the Hilbert-Huang transform method on 3D fluid ...

Flow Field Evolution of a Decaying Sunspot [PDF]

, 2007
We study the evolution of the flows and horizontal proper motions in and around a decaying follower sunspot based on time sequences of two-dimensional spectroscopic observations in the visible and white light imaging data obtained over six days from June~

Experimental Investigation on Atmospheric Pressure Plasma Jet under Locally Divergent Magnet Field

Energies, 2023
Regulating the parameters of the atmospheric pressure plasma jet (APPJ) is meaningful for industrial applications. Since plasma is a typical functional fluid in the magnetic field, it is possible to control the discharge characteristics via the Lorentz ...

Can core-surface flow models be used to improve the forecast of the Earth's main magnetic field? [PDF]

, 2008
[1] Geomagnetic main field models used for navigation are updated every 5 years and contain a forecast of the geomagnetic secular variation for the upcoming epoch. Forecasting secular variation is a difficult task.

Change of water saturation in tight sandstone gas reservoirs near wellbores

Natural Gas Industry B, 2018
Tight sandstone gas reservoirs commonly contain water, so liquid loading often appears near wellbores, leading to production decline and even shutdown of gas wells.

Numerical Study on the Effects of the Multiple Porous Medium Breakwaters on the Propagation of the Solitary Wave

Journal of Marine Science and Engineering, 2023
Submerged breakwater, as an important marine engineering structure, can effectively absorb wave energy and is widely used in marine engineering protection. As a new type of breakwater, porous medium breakwater has a certain influence on wave propagation.

Strong confinement of active microalgae leads to inversion of vortex flow and enhanced mixing

eLife, 2021
Microorganisms swimming through viscous fluids imprint their propulsion mechanisms in the flow fields they generate. Extreme confinement of these swimmers between rigid boundaries often arises in natural and technological contexts, yet measurements of ...

Effect of an electric field on an intermittent granular flow [PDF]

, 2010
Granular gravity driven flows of glass beads have been observed in a silo with a flat bottom. A DC high electric field has been applied perpendicularly to the silo to tune the cohesion. The outlet mass flow has been measured.
