Attached eddy model of wall turbulence
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
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 …

Hot-wire spatial resolution issues in wall-bounded turbulence
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
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 …

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