Condensation of microturbulence-generated shear flows into global modes [PDF]

, 2000
In full flux-surface computer studies of tokamak edge turbulence, a spectrum of shear flows is found to control the turbulence level and not just the conventional (0,0)-mode flows.

Investigations of hydraulic transient flows in pressurized pipeline based on 1D traditional and 3D weakly compressible models

Journal of Hydroinformatics, 2021
Transient flow characteristics and dissipation mechanism in pressurized pipeline were investigated based on 1D friction models and 3D turbulence models, where the pressure–density model was combined into the 3D continuity equation allowing for the ...

Clustering and turbulence modulation in particle-laden shear flows [PDF]

Journal of Fluid Mechanics, 2011
AbstractTurbulent fluctuations induce the common phenomenon known as clustering in the spatial arrangement of small inertial particles transported by the fluid. Particles spread non-uniformly, and form clusters where their local concentration is much higher than in nearby rarefaction regions. The underlying physics has been exhaustively analysed in the

Nocturnal boundary layer turbulence regimes analysis during the BLLAST campaign [PDF]

Atmospheric Chemistry and Physics, 2019
A night-time turbulence regime classification, the so-called “HOckey-Stick Transition ” (HOST) theory, proposed by Sun et al. (2012) from the Cooperative Atmosphere–Surface Exchange Study-1999 (CASES-99) is explored using data from the Boundary-Layer ...

An Introduction to Particle Acceleration in Shearing Flows

Galaxies, 2019
Shear flows are ubiquitously present in space and astrophysical plasmas. This paper highlights the central idea of the non-thermal acceleration of charged particles in shearing flows and reviews some of the recent developments.

Three-dimensional smoothed particle hydrodynamics modeling of near-shore current flows over rough topographic surface

Frontiers in Marine Science, 2022
In this study, a three-dimensional (3D) numerical model based on the smoothed particle hydrodynamics (SPH) approach was developed to simulate the near-shore current flows over a rough topographic surface in the coastal area, where the flows are shallow ...

Atmospheric Turbulence Effects on Wind-Turbine Wakes: An LES Study

Energies, 2012
A numerical study of atmospheric turbulence effects on wind-turbine wakes is presented. Large-eddy simulations of neutrally-stratified atmospheric boundary layer flows through stand-alone wind turbines were performed over homogeneous flat surfaces with ...

Turbulent-laminar patterns in shear flows without walls [PDF]

, 2016
Turbulent-laminar intermittency, typically in the form of bands and spots, is a ubiquitous feature of the route to turbulence in wall-bounded shear flows.
