Relativistic Fluid Dynamics: Physics for Many Different Scales [PDF]

open access: yesLiving Reviews in Relativity, 2007
AbstractThe relativistic fluid is a highly successful model used to describe the dynamics of many-particle systems moving at high velocities and/or in strong gravity. It takes as input physics from microscopic scales and yields as output predictions of bulk, macroscopic motion.

Editorial: Mathematical problems in physical fluid dynamics: part I

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2022
Fluid dynamics is a research area lying at the crossroads of physics and applied mathematics with an ever-expanding range of applications in natural sciences and engineering. However, despite decades of concerted research efforts, this area abounds with many fundamental questions that still remain unanswered.

Bianchi Type I Universes with Causal Bulk Viscous Cosmological Fluid [PDF]

open access: yes, 2001
We consider the dynamics of a causal bulk viscous cosmological fluid filled constantly decelerating Bianchi type I space-time. The matter component of the Universe is assumed to satisfy a linear barotropic equation of state and the state equation of the ...

Dynamics of Relativistic Magnetized Blast Waves [PDF]

open access: yes, 2001
The dynamics of a relativistic blast wave propagating through magnetized medium is considered taking into account possible inhomogeneities of density and magnetic field and additional energy supply.

Fundamental understanding of swirling flow pattern in hydrocyclones [PDF]

open access: yes, 2012
This work is concerned with establishing and validating a physics-based model that describes the swirling flow inside hydrocyclones. The physics is embedded in a Computational Fluid Dynamics (CFD) simulation model whose key features are presented and ...

Kelvin-Helmholtz instability is the result of parity-time symmetry breaking

open access: yes, 2018
Parity-Time (PT)-symmetry is being actively investigated as a fundamental property of observables in quantum physics. We show that the governing equations of the classical two-fluid interaction and the incompressible fluid system are PT-symmetric, and ...

"Bernoulli" Levitation

open access: yes, 2002
"Bernoulli" levitation is the basis of many popular counter-intuitive physics demonstrations. However, few of these lend themselves to a quantitative description without recourse to computational fluid dynamics.

Exactly Integrable Dynamics of Interface between Ideal Fluid and Light Viscous Fluid

open access: yes, 2004
It is shown that dynamics of the interface between ideal fluid and light viscous fluid is exactly integrable in the approximation of small surface slopes for two-dimensional flow.

Suppression of elliptic flow in a minimally viscous quark-gluon plasma

open access: yes, 2007
We compute the time evolution of elliptic flow in non-central relativistic heavy-ion collisions, using a (2+1)-dimensional code with longitudinal boost-invariance to simulate viscous fluid dynamics in the causal Israel-Stewart formulation.
