Fluid dynamics of dilatant fluids [PDF]
Physical Review E, 2012 Dense mixture of granules and liquid often shows a sever shear thickening and is called a dilatant fluid. We construct a fluid dynamics model for the dilatant fluid by introducing a phenomenological state variable for a local state of dispersed particles.

Ultrarelativistic fluid dynamics [PDF]
Classical and Quantum Gravity, 2000 This is the first of two papers examining the critical collapse of spherically symmetric perfect fluids with the equation of state P = (Gamma -1)rho. Here we present the equations of motion and describe a computer code capable of simulating the extremely relativistic flows encountered in critical solutions for Gamma <= 2.

Supersymmetric fluid dynamics [PDF]
Physical Review D, 2012 Recently Navier-Stokes (NS) equations have been derived from the duality between the black branes and a conformal fluid on the boundary of AdS_5. Nevertheless, the full correspondence has to be established between solutions of supergravity in AdS_5 and supersymmetric field theories on the boundary.

Classical and Quantum Gravity, 1996 Summary: We present the general energy-momentum tensor for a dynamical string fluid and show that it predicts that strings are very strong during early cosmological times, weak after the inflationary period, and negligible during the late-time evolution of the universe.

Conformal fluid dynamics [PDF]
Nuclear Physics B, 2006 We present a conformal theory of a dissipationless relativistic fluid in 2 space-time dimensions. The theory carries with it a representation of the algebra of 2-$D$ area-preserving diffeomorphisms in the target space of the complex scalar potentials. A complete canonical description is given, and the central charge of the current algebra is calculated.

Advances in Colloid and Interface Science, 2017 Network fluids are structured fluids consisting of chains and branches. They are characterized by unusual physical properties, such as, exotic bulk phase diagrams, interfacial roughening and wetting transitions, and equilibrium and nonequilibrium gels. Here, we provide an overview of a selection of their equilibrium and dynamical properties.

Corrections to Fluid Dynamics [PDF]
Open Systems & Information Dynamics, 2003 We show that a Galilean invariant version of fluid dynamics can be derived by the methods of statistical dynamics using Maxwell's balance equations. The basic equation is non-local, and might replace the Boltzmann equation if the latter turns out not to have global smooth solutions in general.

On internal fluid dynamics [PDF]
Bulletin of Mathematical Sciences, 2012 The paper under review is concerned with the mathematical study of various phenomena arising in fluid dynamics. This study is developed both in symmetric and nonsymmetric cases and over short or long length scales with or without viscous-inviscid interactions. Three dimensional effects are also investigated in the present paper.

Seasonal predictability of baroclinic wave activity
npj Climate and Atmospheric Science, 2021 Midlatitude baroclinic waves drive extratropical weather and climate variations, but their predictability beyond 2 weeks has been deemed low. Here we analyze a large ensemble of climate simulations forced by observed sea surface temperatures (SSTs) and ...
