Three-dimensional lattice Boltzmann model for acoustic waves emitted by a source

Article in Int. J. Comput. Fluid Dyn. (2021)

Three-dimensional lattice Boltzmann model for acoustic waves emitted by a source

Jaouad Benhamou, Salaheddine Channouf, Mohammed Jami, Ahmed Mezrhab, Daniel Henry & Valéry Botton

This paper implements the lattice Boltzmann method to simulate the propagation of sound waves in three dimensions. The numerical model is exercised on the lid-driven cavity flow. Tests are then (...)

Vortex clustering, polarisation and circulation intermittency in classical and quantum turbulence

Article in Nature Communications (2021)

Vortex clustering, polarisation and circulation intermittency in classical and quantum turbulence

Juan Ignacio Polanco, Nicolás P. Müller & Giorgio Krstulovic

The understanding of turbulent flows is one of the biggest current challenges in physics, as no first-principles theory exists to explain their observed spatio-temporal intermittency. Turbulent (...)

Two-dimensional numerical model of Marangoni surfers: From single swimmer to crystallization

Article in Phys. Rev. E (2021)

Two-dimensional numerical model of Marangoni surfers: From single swimmer to crystallization

Clément Gouiller, Christophe Ybert, Cécile Cottin-Bizonne, Florence Raynal, Mickaël Bourgoin & Romain Volk

We numerically study the dynamics of an ensemble of Marangoni surfers in a two-dimensional and unconfined space. The swimmers are modeled as Gaussian sources of surfactant generating surface (...)

Effect of shaping on turbulent dynamics in reversed-field pinch simulations

Article in J. Plasma Phys. (2021)

Effect of shaping on turbulent dynamics in reversed-field pinch simulations

Robert Chahine, Kai Schneider & Wouter Bos

We study the influence of the shape of the plasma container on the dynamics of the reversed-field pinch (RFP). The geometries we consider are periodic cylinders with elliptical and (...)

Impact of Switchbacks on Turbulent Cascade and Energy Transfer Rate in the Inner Heliosphere

C. S. Hernández, L. Sorriso-Valvo, R. Bandyopadhyay, A. Chasapis, C. L. Vásconez, R. Marino & O. Pezzi

Recent Parker Solar Probe (PSP) observations of inner heliospheric plasma have shown an abundant presence of Alfvénic polarity reversal of the magnetic field, known as "switchbacks." While their (...)

Existence of positive skewness of velocity gradient in early transition

Article in Phys. Rev. Fluids (2021)

Existence of positive skewness of velocity gradient in early transition

H. K. Zhao, Y. W. Liu, L. Shao, L. Fang & M. Dong

The present study uses direct numerical simulations to calculate two different transitional flows from laminar flow to turbulence, that is, the two-scale wake flow and the two-dimensional (...)

Statistical mechanics of the Euler equations without vortex stretching

Article in J. Fluid Mech. (2021)

Statistical mechanics of the Euler equations without vortex stretching

Tong Wu & Wouter Bos

We consider the relaxation to thermal equilibrium of the Galerkin-truncated Euler equations in three dimensions, from which vortex stretching is removed. We prove that helicity and enstrophy are (...)

Article in J. Turbomachinery (2022)

Unsteady lattice Boltzmann simulations of corner separation in a compressor cascade

Jérôme Boudet, Emmanuel Lévêque & Hatem Touil

Lattice Boltzmann simulations of corner separation flow in a compressor cascade are presented. The lattice Boltzmann approach is rather new in the context of turbomachinery, and the configuration (...)
