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…

Revisiting "bursts" in wall-bounded turbulent flows
Subharthi Chowdhuri, Tirtha Banerjee
Turbulent signals are known to exhibit burst-like activities, which affect the turbulence statistics at both large and small scales of the flow. In our study, we pursue this proble…
