Intrinsic rotation in tokamaks: theory [PDF]

open access: yes, 2015
Self-consistent equations for intrinsic rotation in tokamaks with small poloidal magnetic field $B_p$ compared to the total magnetic field $B$ are derived.

Inverse design of mesoscopic models for compressible flow using the Chapman-Enskog analysis

open access: yesAdvances in Aerodynamics, 2021
In this paper, based on simplified Boltzmann equation, we explore the inverse-design of mesoscopic models for compressible flow using the Chapman-Enskog analysis. Starting from the single-relaxation-time Boltzmann equation with an additional source term,

Suppression of the Spatial Hydrodynamic Instability in Scale-Resolving Simulations of Turbulent Flows Inside Lined Ducts

open access: yesFluids, 2023
This paper addresses one of the major obstacles arising in the high-fidelity scale-resolving simulations of turbulent flows inside ducts with the walls covered by acoustic liners in order to attenuate the sound radiated from the duct.

Turbulent thermalization [PDF]

open access: yesPhysical Review D, 2004
We study, analytically and with lattice simulations, the decay of coherent field oscillations and the subsequent thermalization of the resulting stochastic classical wave-field. The problem of reheating of the Universe after inflation constitutes our prime motivation and application of the results. We identify three different stages of these processes.

Aerodynamic generation of electric fields in turbulence laden with charged inertial particles

open access: yesNature Communications, 2018
How lightning occurs in dusty atmospheres remains largely unknown because of the complexity of the turbulent flows involved. Di Renzo and Urzay reveal a flow-driven mechanism of charge separation by simulating turbulence laden with hundreds of millions ...

Unified energy law for fluctuating density wave orders in cuprate pseudogap phase

open access: yesCommunications Physics, 2022
The origin of the pseudogap in the cuprates and how it is related to the mechanism of their superconductivity has been a topic of long standing debate. Here, the authors suggest that the pseudogap is governed by a unified energy law the basis for which ...

Variability of Internally Generated Turbulence in an Estuary, from 100 Days of Continuous Observations [PDF]

open access: yes, 2009
We present detailed observations of internally generated turbulence in a sheared, stratified natural flow, as well as an analysis of the external factors leading to its generation and temporal variability.

Publisher Correction: Aerodynamic generation of electric fields in turbulence laden with charged inertial particles

open access: yesNature Communications, 2018
The original version of this Article contained an error in the last sentence of the second paragraph of the ‘Atmospheric rarefaction effects’ section of the Results, which incorrectly read ‘The other one emulates the rarefied, CO2-rich Martian atmosphere

Criteria of tracking vortex surfaces in turbulent-like flows

open access: yesAdvances in Aerodynamics, 2022
We propose criteria of tracking vortex surfaces in complex flows based on the vortex-surface field (VSF). The criteria characterize the accuracy and Lagrangian tracking performance of the numerical VSF solution, and determine the time period when the ...

Vortices and turbulence in trapped atomic condensates [PDF]

open access: yes, 2013
After over a decade of experiments generating and studying the physics of quantized vortices in atomic gas Bose-Einstein condensates, research is beginning to focus on the roles of vortices in quantum turbulence, as well as other measures of quantum ...
