Local Causal States and Discrete Coherent Structures [PDF]
Chaos, 2018 Coherent structures form spontaneously in nonlinear spatiotemporal systems and are found at all spatial scales in natural phenomena from laboratory hydrodynamic flows and chemical reactions to ocean, atmosphere, and planetary climate dynamics ...

Coherent Structures and Spectral Energy Transfer in Turbulent Plasma: A Space-Filter Approach. [PDF]
Physical Review Letters, 2017 Plasma turbulence at scales of the order of the ion inertial length is mediated by several mechanisms, including linear wave damping, magnetic reconnection, the formation and dissipation of thin current sheets, and stochastic heating.

Vortical Structures in High-Reynolds-Number Jet Indicating Edgetone Oscillation
Journal of Fluid Science and Technology, 2007 Coherent vortical structures in a high-Reynolds number turbulent jet indicating edgetone oscillations are extracted from velocity and pressure data. Three statistical quantities are adopted as the candidate indicators of coherent structures; (i) phase ...

Structured transmittance illumination coherence holography
Scientific Reports, 2022 AbstractThe coherence holography offers an unconventional way to reconstruct the hologram where an incoherent light illumination is used for reconstruction purposes, and object encoded into the hologram is reconstructed as the distribution of the complex coherence function. Measurement of the coherence function usually requires an interferometric setup

Studying geometric structures in meso-scale flows
Frontiers in Environmental Science, 2014 Geometric shapes of coherent structures such as ramp or cliff like signals, step changes and waves, are commonly observed in meteorological temporal series and dominate the turbulent energy and mass exchange between the atmospheric surface layer and the ...

On the Wake Dynamics of an Oscillating Cylinder via Proper Orthogonal Decomposition
Fluids, 2022 The coherent structures and wake dynamics of a two-degree-of-freedom vibrating cylinder with a low mass ratio at Re=5300 are investigated by means of proper orthogonal decomposition (POD) of a numerical database generated using large-eddy simulations ...

Energy and Entropy in Turbulence Decompositions
Entropy, 2019 The role of energy and entropy in the decomposition of turbulent velocity flow-fields is shown in this paper. Decomposition methods based on the energy concept are taken into account—proper orthogonal decomposition (POD) and its extension bi ...

On Rayleigh-Taylor and Richtmyer-Meshkov Dynamics With Inverse-Quadratic Power-Law Acceleration
Frontiers in Applied Mathematics and Statistics, 2022 Rayleigh-Taylor (RT) and Richtmyer-Meshkov (RM) instabilities occur in many situations in Nature and technology from astrophysical to atomic scales, including stellar evolution, oceanic flows, plasma fusion, and scramjets.
