Non-linear Black Hole Ringdowns: an Analytical Approach
Davide Perrone, Thomas Barreira, Alex Kehagias +1
Due to the nature of gravity, non-linear effects are left imprinted in the quasi-normal modes generated in the ringdown phase of the merger of two black holes. We offer an analytic…
Investigating the magnitude and temporal localization of inertial particle mixing in turbulent channel flows
D. Perrone, J. G. M Kuerten, L. Ridolfi +1
Mixing of inertial point particles in a turbulent channel flow at Reτ = 950 is investigated by means of direct numerical simulations. We consider inertial particles, at varying Sto…
Explaining Nonlinearities in Black Hole Ringdowns from Symmetries
Alex Kehagias, Davide Perrone, Antonio Riotto +1
It has been recently pointed out that nonlinear effects are necessary to model the ringdown stage of the gravitational waveform produced by the merger of two black holes giving ris…
Visibility analysis of boundary layer transition
Davide Perrone, Luca Ridolfi, Stefania Scarsoglio
We study the transition to turbulence in a flat plate boundary layer by means of visibility analysis of velocity time-series extracted across the flow domain. By taking into accoun…
Network analysis of Reynolds number scaling in wall-bounded Lagrangian mixing
Davide Perrone, J. G. M Kuerten, Luca Ridolfi +1
The dispersion and mixing of passive particles in a turbulent channel flow is investigated by means of a network-based representation of their motion. We employ direct numerical si…
Wall-induced anisotropy effects on turbulent mixing in channel flow: A network-based analysis
Davide Perrone, J. G. M. Kuerten, Luca Ridolfi +1
Turbulent mixing is studied in the Lagrangian framework with an approach based on the complex network formalism. We consider the motion of passive, noninertial particles inside a t…
