A Two-dimensional Model of Shear-flow Transition
We explore a two-dimensional dynamical system modeling transition in shear flows to try to understand the nature of an ’edge’ state. The latter is an invariant set in phase space separating the basin of attraction B of the laminar state into two parts distinguished from one another by the nature of relaminarizing orbits. The model is parametrized by R, a stand-in for Reynolds number. The origin...
متن کاملTwo-dimensional perturbations in a scalar model for shear banding.
We present an analytical study of a toy model for shear banding, without normal stresses, which uses a piecewise linear approximation to the flow curve (shear stress as a function of shear rate). This model exhibits multiple stationary states, one of which is linearly stable against general two-dimensional perturbations. This is in contrast to analogous results for the Johnson-Segalman model, w...
متن کاملShear viscosity and shear thinning in two-dimensional Yukawa liquids.
A two-dimensional Yukawa liquid is studied using two different nonequilibrium molecular dynamics simulation methods. Shear viscosity values in the limit of small shear rates are reported for a wide range of Coulomb coupling parameter and screening lengths. At high shear rates it is demonstrated that this liquid exhibits shear thinning; i.e., the viscosity eta diminishes with increasing shear ra...
متن کاملa study on insurer solvency by panel data model: the case of iranian insurance market
the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.
Contribution TWO - DIMENSIONAL SONOELASTOGRAPHIC SHEAR VELOCITY IMAGING
We introduce a novel 2-D sonoelastographic technique for estimating local shear velocities from propagating shear wave interference patterns (termed crawling waves) in this paper. A relationship between the local crawling wave spatial phase derivatives and local shear wave velocity is derived, with phase derivatives estimated using a 2-D autocorrelation technique. Comparisons were made between ...
