Dynamic Mode Decomposition for Large-Scale Coherent Structure Extraction in Shear Flows
IEEE Transactions on Visualization and Computer Graphics, 2021 Large-scale structures have been observed in many shear flows which are the fluid generated between two surfaces moving with different velocity. A better understanding of the physics of the structures (especially large-scale structures) in shear flows ...

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 ...

Predictions of turbulent shear flows using deep neural networks [PDF]
Physical Review Fluids, 2019 In the present work we assess the capabilities of neural networks to predict temporally evolving turbulent flows. In particular, we use the nine-equation shear flow model by Moehlis et al. [New J. Phys.

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.

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 ...

A New “λ2” Term for the Spalart–Allmaras Turbulence Model, Active in Axisymmetric Flows
Flow Turbulence and Combustion, 2021 The new term belongs in the “basic,” free-shear-flow part of the Spalart–Allmaras (SA) model, and extends an idea of the Secundov team, incorporated in the νt-92 model.

Turbulent shear flow of solids [PDF]
, 2021 Abstract The term ‘solid-state turbulence’ may sound like an oxymoron, but in fact it is not. In this article we demonstrate that solid-state turbulence may emerge owing to a defining property of the solid state: the ability of a solid to retain its shape.
