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…
Load estimation in unsteady flows from sparse pressure measurements: Application of transition networks to experimental data
Giovanni Iacobello, Frieder Kaiser, David E. Rival
Inspired by biological swimming and flying with distributed sensing, we propose a data-driven approach for load estimation that relies on complex networks. We exploit sparse, real-…
Large-to-small scale frequency modulation analysis in wall-bounded turbulence via visibility networks
Giovanni Iacobello, Luca Ridolfi, Stefania Scarsoglio
Scale interaction is studied in wall-bounded turbulence by focusing on the frequency modulation (FM) mechanism of large scales on small scale velocity fluctuations. Differently fro…
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…
A review on turbulent and vortical flow analyses via complex networks
Giovanni Iacobello, Luca Ridolfi, Stefania Scarsoglio
Turbulent and vortical flows are ubiquitous and their characterization is crucial for the understanding of several natural and industrial processes. Among different techniques to s…
Experimental investigation of vertical turbulent transport of a passive scalar in a boundary layer: statistics and visibility graph analysis
Giovanni Iacobello, Massimo Marro, Luca Ridolfi +2
The dynamics of a passive scalar plume in a turbulent boundary layer is experimentally investigated via vertical turbulent transport time-series. Data are acquired in a rough-wall…
Lagrangian network analysis of turbulent mixing
Giovanni Iacobello, Stefania Scarsoglio, J. G. M. Kuerten +1
A temporal complex network-based approach is proposed as a novel formulation to investigate turbulent mixing from a Lagrangian viewpoint. By exploiting a spatial proximity criterio…
Spatial characterization of turbulent channel flow via complex networks
Giovanni Iacobello, Stefania Scarsoglio, J. G. M. Kuerten +1
A network-based analysis of a turbulent channel flow numerically solved at is proposed as an innovative perspective for the spatial characterization of the flow field. T…
Visibility graph analysis of wall turbulence time-series
Giovanni Iacobello, Stefania Scarsoglio, Luca Ridolfi
The spatio-temporal features of the velocity field of a fully-developed turbulent channel flow are investigated through the natural visibility graph (NVG) method, which is able to…
Complex Networks Unveiling Spatial Patterns in Turbulence
Stefania Scarsoglio, Giovanni Iacobello, Luca Ridolfi
Numerical and experimental turbulence simulations are nowadays reaching the size of the so-called big data, thus requiring refined investigative tools for appropriate statistical a…
