Universality of scaling and multiscaling in turbulent symmetric binary fluids
Universality of scaling turbulent symmetric binary fluids
2010/12/28
We elucidate the universal scaling and multiscaling properties of the nonequilibrium steady states (NESS) in a driven symmetric binary fluid (SBF) mixture in its homogeneous miscible phase in three di...
We consider the canonical quantization of an ordinary fluid. The resulting long-distance effective field theory is derivatively coupled, and therefore strongly coupled in the UV. The system however ex...
Here we show how an anisotropic uid in the di usion limit can be equivalent to an isotropic
uid in the streaming out limit, in spherical symmetry.

2010/11/24
We report a systematic molecular dynamics study of the isochoric equilibration of hard-sphere
fluids in their metastable regime close to the glass transition. The thermalization process starts with t...

Results for transport properties, in conjunction with phase behavior and thermodynamics, are
presented at the criticality of a binary Lennard-Jones fluid from Monte Carlo and molecular dy-
namics si...

Runaway expansion in confined quasi-2D plasmas and vortex fluids
Runaway expansion quasi-2D plasmas vortex fluids
2010/11/11
The confined, quasi-two-dimensional guiding center plasma and a system of interacting line vortices in an ideal fluid are examples of Hamiltonian systems with infinite interaction distances. The exis...
Plane-symmetric spacetimes with positive cosmological constant. The case of stiff fluids
Plane-symmetric spacetimes positive cosmological constant stiff fluids
2010/12/20
We consider plane-symmetric spacetimes satisfying Einstein’s field equations with positive cosmological constant, when the matter is a fluid whose pressure is equal to its mass-energy density (i.e. a ...
Gravity-analogy in one-dimensional ideal Fermi fluids and Burgers' equation
Gravity-analogy one-dimensional ideal Fermi fluids Burgers' equation
2010/11/11
An hydrodynamic description of a one-dimensional flow of an ideal Fermi fluid is constructed from a semiclassical approximation. For an initially fully degenerate fluid, Euler and continuity hydrodyna...
Structural anisotropy and orientation-induced Casimir repulsion in fluids
Structural anisotropy orientation-induced Casimir repulsion fluids
2010/10/21
We demonstrate that the Casimir force between two dielectric slabs containing metallic wires will strongly depend on the relative orientation of the wires and can even change sign with rotation when a...

Stochastic Shear Thickening Fluids:Strong Convergence Galerkin Approximation Energy Equality
2010/12/3
We consider a SPDE (stochastic partial differential equation) which describes the velocity field of a viscous, incompressible non-Newtonian fluid subject to a random force.Here, the extra stress tenso...

Remarks on Oldroyd-B Related Complex Fluids Models
2010/11/26
We prove global existence and uniqueness of solutions of Oldroyd-B systems with relatively small data in Rd, in a large functional setting (C \ L1). This is a stability result,
solutions select an e...

2010/12/13
We study the local-in-time hydrodynamic limit of the relativistic Boltzmann equation using a Hilbert expansion. More speci cally, we prove the existence of local solutions to the relativistic Boltzman...

2010/12/3
We consider a singular limit problem for the Navier-Stokes system of a rotating compressible fluid, where the Rossby and Mach numbers tend simultaneously to zero. The limit problem
is identified as t...
