The network of interactions among fluid elements and coherent structures gives rise to the
incredibly rich dynamics of vortical flows. These interactions can be described with the use …

The presence of very-large-scale motions in wall-bounded turbulent flows is commonly
associated with their footprint in the form of the superposition of the large scales at the wall …

Turbulence in the roughness sublayer (RSL) is inhomogeneous compared with that in the
inertial sublayer (ISL) of the atmospheric surface layer (ASL) over urban areas. Drag …

Time irreversibility is a distinctive feature of non-equilibrium phenomena such as turbulent
flows, where irreversibility is mainly associated with an energy cascade process. The …

The convection velocity (UC) of turbulent structures has been studied in adverse-pressure-
gradient (APG) turbulent boundary layers (TBLs) for a wide range of Reynolds numbers R e …

In this paper, we study the artificially thickened boundary layer flows downstream of the
tripping configuration that consists of a set of trip wires of varying diameters. Single-point hot …

Large-scale intermittency is a widely observed phenomenon in convective surface layer
turbulence that induces non-Gaussian temperature statistics, while such a signature is not …

Turbulent signals are known to exhibit burstlike activities, which affect the turbulence
statistics at both large and small scales of the flow. In our study, we pursue this problem from …

This paper reports a novel methodology that allows the intensity of, and the underlying
mechanism for, the amplitude and length-scale modulation (amplification or attenuation) of …

In turbulent flows, energy production is associated with highly organized structures, known
as coherent structures. Since these structures are three dimensional, their detection remains …
