NOTE ON GLOBAL REGULARITY FOR 2D OLDROYD-B FLUIDS WITH DIFFUSIVE STRESS
Oldroyd-B, complex uids Fokker-Planck equations blow up global existence Euler equations Navier-Stokes equations kinetic equations
2014/4/3
We prove global regularity of solutions of Oldroyd-B equations in 2 spatial dimensions with spatial di usion of the polymeric stresses.
Tensorial representations of Reynolds-stress redistribution
Tensorial representations Reynolds-stress redistribution
2011/3/2
The purpose of the present note is to contribute in clarifying the relation between representation bases used in the closure for the redistribution (pressure-strain) tensor fi j , and to propose a rep...
One-loop stress tensors for scalar and spinor fields on the homogeneous spaces with G-invariant metrics
One-loop stress tensors for scalar spinor fields homogeneous spaces G-invariant metrics
2011/2/28
Vacuum expectation value of the stress-energy-momentum tensor for scalar and spinor fields is obtainted on the homogeneous space with G-invariant metrics using the orbits of coadjoint representation o...
Influences of rotation, magnetic field, initial stress, and gravity on Rayleigh waves in a homogeneous orthotropic elastic half-space
Electric intensity initial-stress, rotation Rayleigh wave velocity
2010/9/20
The aim of this paper is to investigate the influences of rotation, magnetic field, initial stress, and gravity field on Rayleigh waves in a homogeneous orthotropic elastic medium. The government equa...
Effect of wall shear stress in the blood flow of two layers in the vessels through stenosis region
Wall shear stress Symmetric Stenosis Blood Flow of Two Layers
2010/9/27
In this paper the mathematical models have been developed to study the effect of wall shear stress in arteries of stenosis, where the blood flow is assumd to behave like a couple stress fluid, periphe...
Study of three-dimensional crack fronts under plane stress using a phase field model
Materials Science (cond-mat.mtrl-sci) Other Condensed Matter (cond-mat.other) Pattern Formation and Solitons (nlin.PS)
2010/11/11
The shape of a crack front propagating through a thin sample is studied using a phase field model. The model is shown to have a well defined sharp interface limit. The crack front is found to be an el...
On stability of rolls near the onset of convection in a layer with stress-free boundaries
stress-free boundaries linear stability
2010/4/2
We consider a classical problem of linear stability of convective rolls in a plane layer with stress-free horizontal boundaries near the onset of convection. The problem has been studied by a number o...
