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 …

Log-layer mismatch refers to a chronic problem found in wall-modeled large-eddy simulation
(WMLES) or detached-eddy simulation, where the modeled wall-shear stress deviates from …

It is generally believed that the temperature and the velocity fields are highly coupled in
compressible wall-bounded turbulence. In the present study, we employ a linear model, ie …

According to Townsend's attached eddy hypothesis (AEH), a boundary layer flow is
comprised of wall-attached eddies, but to extract the part of the flow whose statistical …

We develop a new methodology to assess the streamwise inclination angles (SIAs) of the
wall-attached eddies populating the logarithmic region with a given wall-normal height. To …

Physical representation of coherent motions in wall-bounded turbulence satisfying
Townsend's attached-eddy hypothesis (AEH) is still an open question to be debated. Here …

At high Reynolds numbers, the logarithmic range in wall-bounded flows spans many scales.
An important conceptual modeling framework of the logarithmic range is Townsend's …

The inner–outer interaction model (Marusic et al., Science, vol. 329, 2010, pp. 193–196) and
the attached-eddy model (Townsend, Cambridge University Press, 1976) are two …

This paper takes the perspective of a user of direct-numerical-simulation (DNS) data and
quantifies the uncertainties in DNS statistics for plane channel flows. We focus on high-order …

A growing body of studies supports the existence of Townsend's wall-attached eddies in wall
turbulence under the condition of sufficiently high Reynolds numbers. In the present work …
