Ladder of information limits on prediction for reduced-order models
Adrian Lozano-Duran
What can and cannot be predicted by a model when only limited information is available? We answer this question by constructing a ladder of information limits that organizes predic…
Decomposing causality into its synergistic, unique, and redundant components
Álvaro Martínez-Sánchez, Gonzalo Arranz, Adrián Lozano-Durán
Causality lies at the heart of scientific inquiry, serving as the fundamental basis for understanding interactions among variables in physical systems. Despite its central role, cu…
Informative and non-informative decomposition of turbulent flow fields
Gonzalo Arranz, Adrian Lozano-Durán
Not all the information in a turbulent field is relevant for understanding particular regions or variables in the flow. Here, we present a method for decomposing a source field int…
Are the dynamics of wall turbulence in minimal channels and larger domain channels equivalent? A graph-theoretic approach
Ahmed Elnahhas, Emma Lenz, Parviz Moin +2
This work proposes two algorithmic approaches to extract critical dynamical mechanisms in wall-bounded turbulence with minimum human bias. In both approaches, multiple types of coh…
Information-theoretic causality and applications to turbulence: energy cascade and inner/outer layer interactions
Adrián Lozano-Durán, Gonzalo Arranz, Yuenong Ling
We introduce an information-theoretic method for quantifying causality in chaotic systems. The approach, referred to as IT-causality, quantifies causality by measuring the informat…
Near-Field Wall-Modeled Large-Eddy Simulation of the NASA X-59 Low-Boom Flight Demonstrator
Emily Williams, Gonzalo Arranz, Adrián Lozano-Durán
Wall-modeled large-eddy simulation (WMLES) is utilized to analyze the experimental aircraft X-59 Quiet SuperSonic Technology (QueSST) developed by Lockheed Martin at Skunk Works fo…
Wall turbulence with constrained energy extraction from mean flow
Adrián Lozano-Durán, Michael Karp, Navid. C. Constantinou
We study the mechanism of energy injection from the mean flow to the fluctuating velocity necessary to maintain wall turbulence. This process is believed to be correctly represente…
Multiscale analysis of the topological invariants in the logarithmic region of turbulent channels at
Adrián Lozano-Durán, Markus Holzner, Javier Jiménez
The invariants of the velocity gradient tensor, and , and their enstrophy and strain components are studied in the logarithmic layer of an incompressible turbulent channel f…
