摘要

The coherent vortex extraction method, a wavelet technique for extracting coherent vortices out of turbulent flows, is applied to simulations of resistive drift-wave turbulence in magnetized plasma (Hasegawa-Wakatani system). The aim is to retain only the essential degrees of freedom, responsible for the transport. It is shown that the radial density flux is carried by these coherent modes. In the quasi-hydrodynamic regime, coherent vortices exhibit depletion of the polarization-drift nonlinearity and vorticity strongly dominates strain, in contrast to the quasiadiabatic regime.

Optimal eddy viscosity for resolvent-based models of coherent structures in turbulent jets

Ethan Pickering, Georgios Rigas, Oliver T. Schmidt, Denis Sipp, Tim Colonius

Summary: Linear resolvent analysis of turbulent mean-flow fields can qualitatively capture characteristics of coherent structures in turbulent flows. By using a data-driven approach to optimize the eddy viscosity, the agreement between resolvent and SPOD modes can be substantially improved, reaching over 90% agreement at certain frequencies. A fixed model for eddy viscosity with a single constant can also provide substantial agreement between different modes in turbulent jets.

Compressibility effects on statistics and coherent structures of compressible turbulent mixing layers

Xiaoning Wang, Jianchun Wang, Shiyi Chen

Summary: This study investigates the effects of compressibility on the statistics and coherent structures of a temporally developing mixing layer through numerical simulations. The results show that as the convective Mach number increases, the streamwise dissipation becomes more effective in suppressing turbulent kinetic energy. At low convective Mach numbers, the mixing layer is accompanied by spanwise Kelvin-Helmholtz rollers, while at higher convective Mach numbers, large-scale high- and low-speed structures dominate. The study also reveals a correlation between high-shearing motions on top of low-speed structures and the clustering of small-scale vortical structures.

Quantification of turbulent structures in and around the boundary region of a turbulent round jet released into counter-flow

Sayahnya Roy, Krishnendu Barman, Koustuv Debnath, Bijoy S. Mazumder

Summary: The study found that the axial jet velocity decays faster in counter turbulence, leading to a reduced entrainment rate of the moving fluid. Eddy intermittency and diffusion depth decreased for jets issued against the current. The kinetic energy budget analysis showed that the pressure diffusion term supplied energy to the jet from the mean background flow.

Experimental observation of turbulent coherent structures in a superfluid of light

A. Eloy, O. Boughdad, M. Albert, P-E Larre, F. Mortessagne, M. Bellec, C. Michel

Summary: This experimental study investigates the nonlinear coherent structures of superfluid light passing an obstacle in an all-optical configuration, revealing different hydrodynamic regimes organized in a unique phase diagram. The focus is on vortices formed in the wake of the obstacle, with analysis of their intensity profile and core radius dependence on healing length. The results pave the way for further research on turbulence in photonic superfluids and offer versatile experimental tools for simulating quantum transport with nonlinear light.

Role of turbulent kinetic energy modulation by particle-fluid interaction in sediment pick-up

Geert H. Keetels, Julien Chauchat, Wim-Paul Breugem

Summary: Reliable prediction of erosion rate of sediment beds is crucial for coastal and river engineering applications. However, the theoretical understanding of scaling relations, particularly for low and high Shields number conditions, is still insufficient. This study investigates the erosion process by analyzing the phase-averaged turbulent kinetic energy (TKE) equations and revealing various TKE modulation mechanisms at high Shields numbers and concentrations. Two scaling laws are derived and validated against extensive experimental data.

Study of the linear models in estimating coherent velocity and temperature structures for compressible turbulent channel flows

Xianliang Chen, Cheng Cheng, Jianping Gan, Lin Fu

Summary: Linear models and stochastic forced linearized equations are used for the estimation of velocity and temperature fluctuations in compressible turbulent channel flows. The eddy-viscosity-enhanced model performs better than the non-enhanced model in terms of coherence and amplitude ratio of velocity, but both deviate significantly from the direct numerical simulation (DNS) regarding temperature prediction. Analysis of the linear operators reveals that the eddy viscosity stabilizes eigenmodes and reduces non-normality of vortical modes, increasing the relative importance of acoustic and entropy modes. After decomposing the cospectrum, it is found that the coherent temperature fluctuation is dominated by advection and other vortical motions rather than compressibility effects. A parameter study of Reynolds and Mach numbers shows good agreement with the incompressible case for high coherence, streamwise-elongated structures.

Role of wave-particle resonance in turbulent transport in toroidal plasmas

G. Dong, Z. Lin

Summary: A clear understanding of wave-particle interaction and associated transport mechanisms is crucial for accurate modeling and predictions in tokamaks. Global gyrokinetic simulations reveal that electron transport is primarily driven by wave-particle resonance in collisionless trapped electron mode (CTEM) turbulence, while ion transport is mostly driven by nonlinear wave-particle scattering in both CTEM and self-consistent ion temperature gradient (ITG) turbulence. These findings emphasize the importance of considering the roles of linear resonance and nonlinear scattering when constructing reduced transport models.

Coherent Soliton States Hidden in Phase Space and Stabilized by Gravitational Incoherent Structures

Josselin Garnier, Kilian Baudin, Adrien Fusaro, Antonio Picozzi

Summary: By increasing the nonlinearity, a system self-organizes into an incoherent localized structure containing hidden coherent soliton states, which are fully immersed in random wave fluctuations and can hardly be identified in usual spatial or spectral domains but clearly unveiled in phase-space representation. The hidden solitons are stabilized and trapped by the incoherent localized structure, and can be observed in nonlocal nonlinear optics experiments through the measurement of the spatial spectrogram. This regime sheds new light on the quantum-to-classical correspondence with gravitational interactions.

Phase and amplitude evolution in the network of triadic interactions of the Hasegawa-Wakatani system

O. D. Guercan, J. Anderson, S. Moradi, A. Biancalani, P. Morel

Summary: This article revisits the phase and amplitude dynamics of the Hasegawa-Wakatani system and finds that a single resonant triad can saturate via phase locking, while non-resonant triads show similar behavior only when one of its legs is a zonal wave number. Additionally, the behavior of the resulting triad pair becomes more complex when an additional triad is included as a reflection.

The dynamo properties of the reversed field pinch velocity field

Robert Chahine, Wouter J. T. Bos, Nicolas Plihon

Summary: This article addresses the question of whether the velocity field in a reversed field pinch (RFP) can amplify a seed magnetic field. Numerical simulations are used to show that the RFP velocity field can indeed amplify a passively advected seed-field, but only when the magnetic Prandtl number is above unity. These observations hold true for both laminar and turbulent RFP flows.

Summary: Alpha particles with energies on the order of megaelectronvolts will be the main source of plasma heating in future magnetic confinement fusion reactors. Instead of heating fuel ions, most of the energy of alpha particles is transferred to electrons in the plasma. Furthermore, alpha particles can also excite Alfvenic instabilities.

Lagrangian conditional statistics and flow topology in edge plasma turbulence

Benjamin Kadoch, Diego del-Castillo-Negrete, Wouter J. T. Bos, Kai Schneider

Summary: This study investigates Lagrangian statistics and particle transport in edge plasma turbulence using the Hasegawa-Wakatani model and its modified version. The role of coherent structures, such as vortices and zonal flows, and their impact on particle Lagrangian statistics are characterized. The study involves computationally intensive long time simulations and analyzes the flow topology using the Lagrangian Okubo-Weiss criterion. The differences between the classical Hasegawa-Wakatani system and its modified version are assessed, and the density flux spectrum and multiscale geometric statistics of particle motion are studied.

A Characteristic Mapping Method for the three-dimensional incompressible Euler equations

Xi -Yuan Yin, Kai Schneider, Jean-Christophe Nave

Summary: We propose an efficient semi-Lagrangian Characteristic Mapping (CM) method for solving the 3D incompressible Euler equations. This method discretizes the flow map associated with the velocity field to evolve advected quantities. By utilizing the properties of the Lie group of volume preserving diffeomorphisms SDiff, long-time deformations can be accurately computed from short-time submaps on coarse grids. The method extends the CM method for 2D incompressible Euler equations.

An EDQNM study of the dissipation rate in isotropic non-equilibrium turbulence

Le Fang, Wouter J. T. Bos

Summary: The energy cascade from large to small scales is a robust feature of three-dimensional turbulence. In statistically steady turbulence, the average dissipation is in equilibrium with the energy injected in the system. Recent investigations have pointed out how this normalised dissipation rate varies in unsteady flows.

Validation and verification of a quasi two-dimensional turbulence model and an eddy detection method for liquid metal magnetohydrodynamics flows

Daniel Suarez, Eduardo Iraola, Joaquim Serrat, Elisabet Mas de les Valls, Shimpei Futatani, Lluis Batet

Summary: This study investigates the flow of liquid metals in breeding blankets of tokamak fusion reactors with an externally applied transverse magnetic field. The effect of magnetohydrodynamics (MHD) under the tokamak magnetic field enhances the laminarization of the flow. Under certain conditions, the combination of Lorentz forces, momentum, and buoyant forces can trigger the formation of vortical structures. A quasi-two-dimensional (Q2D) model is used to study this phenomenon, assuming electrically insulating walls and a high Hartmann number. The application of the bi-dimensional fast Fourier transform (FFT2) is proposed as a suitable method to detect the presence of eddies in the flow domain.

Periodic epidemic outbursts explained by local saturation of clusters

Louis Gostiaux, Wouter J. T. Bos, Jean-Pierre Bertoglio

Summary: Adding spatial locality to the SIR model captures local saturation of an epidemic. The resulting minimal epidemic model with five ordinary differential equations and constant coefficients reproduces slowly decaying periodic outbursts observed in COVID-19 or Spanish flu. It is demonstrated that if immunity decays, even slowly, the model exhibits fully periodic dynamics.
