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…
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…
