Peristaltic flow of a fluid in a porous channel: A study having relevance to flow of bile within ducts in a pathological state
Peristaltic Transport Darcy Number Porosity Velocity Profile Critical Pressure
2011/9/22
Abstract: The paper deals with a theoretical study of the transport of a fluid in a channel, which takes place by the phenomenon of peristalsis. A mathematical analysis of the said problem has been pr...

Stokes’ first problem viscoelastic generalized second grade fluid Integral-balance solution Deborah number
2011/9/21
Abstract: Integral balance solution employing entire domain approximation and the penetration dept concept to the Stokes' first problem of a viscoelastic generalized second grade fluid has been develo...
Fluid dynamics and noise in bacterial cell-cell and cell-surface scattering
Fluid dynamics noise bacterial cell-cell cell-surface scattering
2011/8/4
Abstract: Bacterial processes ranging from gene expression to motility and biofilm formation are constantly challenged by internal and external noise. While the importance of stochastic fluctuations h...
The Penrose Inequality and the Fluid/Gravity Correspondence
Penrose Inequality Fluid/Gravity Correspondence
2010/12/21
Motivated by the fluid/gravity correspondence, we consider the Penrose inequality in the frame-
work of fluid dynamics. In general relativity, the Penrose inequality relates the mass and the entropy ...
The Fluid/Gravity Correspondence: a new perspective on the Membrane Paradigm
The Fluid/Gravity Correspondence the Membrane Paradigm
2010/12/27
This talk gives an overview of the recently-formulated Fluid/Gravity correspondence, which was developed in the context of gauge/gravity duality. Mathematically, it posits that Einstein's equations (...
The shear () and bulk () viscous coefficients have been evaluated for a gluonic fluid. The elastic,gg ! gg and the inelastic, number non-conserving, gg ! ggg processes have been considered as the do...
L.R.S. Bianchi type II Stiff Fluid cosmological model with Decaying Vacuum Energy Density $\Lambda$ in general relativity
LRS Bianchi type II models Cosmological constant
2010/12/20
Locally rotationally symmetric (L.R.S.) Bianchi type II stiff fluid cos-mological model is investigated. To get the deterministic model of the universe, we have assumed a condition A = Bm between metr...
Nematic spin fluid in the tetragonal phase of BaFe2As2
Nematic spin fluid tetragonal phase of BaFe2As2
2010/11/23
Magnetic interactions are generally believed to play a key role in mediating electron pairing for superconductivity in iron arsenides1-4; yet their character is only partially understood5-8. Experimen...
The Fluid/Gravity Correspondence: a new perspective on the Membrane Paradigm
Fluid/Gravity Correspondence new perspective Membrane Paradigm
2010/12/20
Relations between kinematics, geometry and law of reference frame motion are considered. We show, that kinematical tensors define geometry up to a space functional arbitrariness when integrability con...
Effective Theory in Spinfoam Cosmology: A First Order LQG-corrected FRW Cosmology and the Stiff Fluid
Effective Theory Spinfoam Cosmology First Order LQG-corrected FRW Cosmology Stiff Fluid
2010/12/20
We present an effective theory of a basic holomorphic spinfoam cosmology peaked on homoge-
neous isotropic metrics. The quantum-corrected Hamiltonian constraint of this effective theory is motivated ...
Derivation of reduced two-dimensional fluid models via Dirac's theory of constrained Hamiltonian systems
two-dimensional fluid models Dirac's theory Hamiltonian systems
2010/4/1
We present a Hamiltonian derivation of a class of reduced plasma two-dimensional fluid models, an example being the Charney-Hasegawa-Mima equation. These models are obtained from the same parent Hamil...

black brane solutions multicomponent anisotropic fluid
2010/3/18
A family of spherically symmetric solutions with horizon in the model with m-component anisotropic fluid is presented. The metrics are defined on a manifold that contains a product of n-1 Ricci-flat "...
Distinguished hyperbolic trajectories in time-dependent fluid flows:analytical and computational approach for velocity fields defined as data sets
Distinguished hyperbolic trajectories time-dependent fluid flows velocity fields
2009/11/12
In this paper we develop analytical and numerical methods for finding special hyperbolic trajectories that govern geometry of Lagrangian structures in time-dependent vector fields. The vector fields (...
Quantum-like gravity waves and vortices in a classical fluid
Quantum-like gravity waves vortices classical fluid
2010/4/13
We have recently proposed a new general concept of macroscopic quantum-type experiment. It amounts to transform a classical fluid into a quantum-type fluid by the application of a quantum-like potenti...

2010/4/8
We study the Kantowski-Sachs cosmological model filled with viscous fluid in the presence of cosmological term L. To get a deterministic solution, a condition between metric potentials is used. The vi...
