Attached Eddy Model of Wall Turbulence

Annual Review of Fluid Mechanics, 2019
Modeling wall turbulence remains a major challenge, as a sufficient physical understanding of these flows is still lacking. In an effort to move toward a physics-based model, A.A.

Particle-Laden Turbulence: Progress and Perspectives

Annual Review of Fluid Mechanics, 2021
This review is motivated by the fast progress in our understanding of the physics of particle-laden turbulence in the last decade, partly due to the tremendous advances of measurement and simulation capabilities.

Turbulent/Turbulent Entrainment

2021
The interfacial region between two bodies of turbulent fluid was investigated through simultaneous particle image velocimetry (PIV) and planar laser induced fluorescence (PLIF) experiments in the far wake of a circular cylinder. Interface conditioned plots of enstrophy revealed the existence of a turbulent/turbulent interface (TTI) where the enstrophy ...

MHD turbulence [PDF]

open access: yesLiving Reviews in Solar Physics, 2019
AbstractWe review the current status of research in MHD turbulence theory and numerical experiments and their applications to astrophysics and solar science. We introduce general tools for studying turbulence, basic turbulence models, MHD equations and their wave modes. Subsequently, we cover the theories and numerics of Alfvénic turbulence, imbalanced

Intermittency and turbulence

Physical Review Letters, 1991
Summary: We suggest a mechanism for the appearance of intermittency in fully developed turbulence consistent with the pictures recently presented by \textit{R. H. Kraichnan} [{}Phys. Rev. Lett. 65, No. 5, 575--578 (1990; Zbl 1050.76546)]{} and \textit{She} [{}Phys. Rev. Lett. 66, 600 ff. (1991)]{}.

Laminar-Turbulent Transition and Turbulence

2014
The state of the boundary layer, laminar or turbulent, influences the drag, the performance of the wing, of stabilization and control devices etc., and the flight characteristics of an airplane. A given flight vehicle is considered as “transition insensitive”, if the location of laminar-turbulent transition does not affect these items.
