Surface roughness can significantly influence the fluid dynamics and heat transfer in
convective flows by inducing perturbations in the velocity profile which affect surface drag …

Understanding, modeling and control of the high-speed wall-bounded transition and
turbulence not only receive wide academic interests but also are vitally important for high …

We report the characteristics of wall shear stress (WSS) and wall heat flux (WHF) from direct
numerical simulation (DNS) of a spatially develo** zero-pressure-gradient supersonic …

In this work, the linear responses of turbulent mean flow to both harmonic and stochastic
forcing are investigated for supersonic channel flow. Well-established universal relations are …

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 …

Non-equilibrium wall turbulence with mean-flow three-dimensionality is ubiquitous in
geophysical and engineering flows. Under these conditions, turbulence may experience a …

Turbulent flows in the presence of walls may be apprehended as a collection of momentum-
and energy-containing eddies (energy-eddies), whose sizes differ by many orders of …
