Attached eddy model of wall turbulence

I Marusic, JP Monty - Annual Review of Fluid Mechanics, 2019 - annualreviews.org
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, AA …

High–Reynolds number wall turbulence

AJ Smits, BJ McKeon, I Marusic - Annual Review of Fluid …, 2011 - annualreviews.org
We review wall-bounded turbulent flows, particularly high–Reynolds number, zero–pressure
gradient boundary layers, and fully developed pipe and channel flows. It is apparent that the …

A critical-layer framework for turbulent pipe flow

BJ McKeon, AS Sharma - Journal of Fluid Mechanics, 2010 - cambridge.org
A model-based description of the scaling and radial location of turbulent fluctuations in
turbulent pipe flow is presented and used to illuminate the scaling behaviour of the very …

Large-scale amplitude modulation of the small-scale structures in turbulent boundary layers

R Mathis, N Hutchins, I Marusic - Journal of Fluid Mechanics, 2009 - cambridge.org
In this paper we investigate the relationship between the large-and small-scale energy-
containing motions in wall turbulence. Recent studies in a high-Reynolds-number turbulent …

Hot-wire spatial resolution issues in wall-bounded turbulence

N Hutchins, TB Nickels, I Marusic… - Journal of Fluid …, 2009 - cambridge.org
Careful reassessment of new and pre-existing data shows that recorded scatter in the hot-
wire-measured near-wall peak in viscous-scaled streamwise turbulence intensity is due in …

Pressure gradient effects on the large-scale structure of turbulent boundary layers

Z Harun, JP Monty, R Mathis, I Marusic - Journal of Fluid Mechanics, 2013 - cambridge.org
Research into high-Reynolds-number turbulent boundary layers in recent years has brought
about a renewed interest in the larger-scale structures. It is now known that these structures …

Amplitude and frequency modulation in wall turbulence

B Ganapathisubramani, N Hutchins… - Journal of Fluid …, 2012 - cambridge.org
In this study we examine the impact of the strength of the large-scale motions on the
amplitude and frequency of the small scales in high-Reynolds-number turbulent boundary …

Model-based scaling of the streamwise energy density in high-Reynolds-number turbulent channels

R Moarref, AS Sharma, JA Tropp… - Journal of Fluid …, 2013 - cambridge.org
We study the Reynolds-number scaling and the geometric self-similarity of a gain-based,
low-rank approximation to turbulent channel flows, determined by the resolvent formulation …

Three-dimensional conditional structure of a high-Reynolds-number turbulent boundary layer

N Hutchins, JP Monty… - Journal of Fluid …, 2011 - cambridge.org
An array of surface hot-film shear-stress sensors together with a traversing hot-wire probe is
used to identify the conditional structure associated with a large-scale skin-friction event in a …

Direct numerical simulation of a 30R long turbulent pipe flow at R+= 685: large-and very large-scale motions

X Wu, JR Baltzer, RJ Adrian - Journal of Fluid Mechanics, 2012 - cambridge.org
Fully developed incompressible turbulent pipe flow at Reynolds number (based on bulk
velocity) and Kármán number is simulated in a periodic domain with a length of pipe radii …
