On the limits of Taylor hypothesis in forest clearcut flow: Effects of random sweeping and an elliptic model analysis
Subharthi Chowdhuri, Ivan Mammarella, Olli Peltola
Taylor's hypothesis (TH) converts temporal observations to spatial information of the flow while carrying out measurements on a micrometeorological tower. Other than TH, there exis…
-moments reveal the scales of momentum transport in dense canopy flows
Subharthi Chowdhuri, Olli Peltola
The interaction between a dense forest canopy and atmosphere is a complex fluid-dynamical problem with a wide range of practical applications, spanning from the aspects of carbon s…
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…
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…
Coherent structures at the origin of time irreversibility in wall turbulence
Giovanni Iacobello, Subharthi Chowdhuri, Luca Ridolfi +2
Time irreversibility is a distinctive feature of non-equilibrium phenomena such as turbulent flows, where irreversibility is mainly associated with an energy cascade process. An Eu…
A scale-wise analysis of intermittent momentum transport in dense canopy flows
Subharthi Chowdhuri, Khaled Ghannam, Tirtha Banerjee
We investigate the intermittent dynamics of momentum transport and its underlying time scales in the near-wall region of the neutrally stratified atmospheric boundary layer in the…
Visibility network analysis of large-scale intermittency in convective surface layer turbulence
Subharthi Chowdhuri, Giovanni Iacobello, Tirtha Banerjee
Large-scale intermittency is a widely observed phenomenon in convective surface layer turbulence that induces non-Gaussian temperature statistics, while such signature is not obser…
Persistence behaviour of heat and momentum fluxes in convective surface layer turbulence
Subharthi Chowdhuri, Thara V Prabha, Tirtha Banerjee
The characterization of heat and momentum fluxes in wall-bounded turbulence is of paramount importance for a plethora of applications, ranging from engineering to Earth sciences. H…
Temperature profiles, plumes and spectra in the surface layer of convective boundary layers
Keith G. McNaughton, Subharthi Chowdhuri
We survey temperature patterns and heat transport in convective boundary layers (CBLs) from the perspective that these are emergent properties of far-from-equilibrium, complex dyna…
Unravelling the turbulent structures of temperature variations during a wind gust event: a case study
Subharthi Chowdhuri, Kiran Todekar, Palani Murugavel +2
The simultaneous observations from a Doppler weather radar and an instrumented micrometeorological tower, offer an opportunity to dissect the effects of a gust front on the surface…
Persistence analysis of velocity and temperature fluctuations in convective surface layer turbulence
Subharthi Chowdhuri, Tamás Kalmár-Nagy, Tirtha Banerjee
Persistence is defined as the probability that the local value of a fluctuating field remains at a particular state for a certain amount of time, before being switched to another s…
Revisiting the role of intermittent heat transport towards Reynolds stress anisotropy in convective turbulence
Subharthi Chowdhuri, Siddharth Kumar, Tirtha Banerjee
Thermal plumes are the energy containing eddy motions that carry heat and momentum in a convective boundary layer. The detailed understanding of their structure is of fundamental i…
