On the large-scale vertical velocity intermittency of turbulent wall flows
Tirtha Banerjee, Elia Buono, Costantino Manes +6
Large-scale intermittency in the vertical velocity (LSI) has received significant attention in studies of coherent structures and their detection using data-driven approaches. Howe…

Quantifying small-scale anisotropy in turbulent flows
Subharthi Chowdhuri, Tirtha Banerjee
The verification of whether small-scale turbulence is isotropic remains a grand challenge. The difficulty arises because the presence of small-scale anisotropy is tied to the dissi…

Level-crossings reveal organized coherent structures in a turbulent time series
Subharthi Chowdhuri, Tirtha Banerjee
In turbulent flows, energy production is associated with highly organized structures, known as coherent structures. Since these structures are three-dimensional, their detection re…
