One-point and two-point statistics of homogeneous isotropic decaying turbulence with variable viscosity
Michael Gauding, Luminita Danaila, Emilien Varea
The decay of homogeneous isotropic turbulence in a variable viscosity fluid with a viscosity ratio up to 15 is analyzed by means of highly resolved direct numerical simulations (DN…
High-order structure functions for passive scalar fed by a mean gradient
Michael Gauding, Luminita Danaila, Emilien Varea
Transport equations for even-order structure functions are written for a passive scalar mixing fed by a mean scalar gradient, with a Schmidt number . Direct numerica…
On the self-similarity of line segments in decaying homogeneous isotropic turbulence
Michael Gauding, Lipo Wang, Jens Henrik Goebbert +3
The self-similarity of a passive scalar in homogeneous isotropic decaying turbulence is investigated by the method of line segments (M. Gauding et al., Physics of Fluids 27.9 (2015…
Features of Transition to Turbulence in Sudden Expansion Pipe Flows
Minh Quan Nguyen, Benoit Lebon, Mostafa Safdari Shadloo +2
The complex flow features resulting from the laminar-turbulent transition (LTT) in a sudden expansion pipe flow, with expansion ratio of 1:2 subjected to an inlet vortex perturbati…
Structural, Dynamical and Symbolic Observability: From Dynamical Systems to Networks
Luis A. Aguirre, Leonardo L. Portes, Christophe Letellier
The concept of observability of linear systems initiated with Kalman in the mid 1950s. Roughly a decade later, the observability of nonlinear systems appeared. By such definitions…
A nonlinear graph-based theory for dynamical network observability
Christophe Letellier, Irene Sendiña-Nadal, Luis A. Aguirre
A faithful description of the state of a complex dynamical network would require, in principle, the measurement of all its variables, an infeasible task for systems with practi…
