Centrifugal Destabilization and Restabilization of Plane Shear Flows
نویسنده
چکیده
The ow of an incompressible viscous uid between parallel plates becomes unstable when the plates are tumbled. As the tumbling rate increases, the ow restabilizes. This phenomenon is elucidated by path-following techniques. The solution of the Navier-Stokes equations is approximated by spectral techniques. The linear stability of these solutions is studied.

Calculation of the relativistic bulk tensor and shear tensor of relativistic accretion flows in the Kerr metric.
In this paper, we calculate the relativistic bulk tensor and shear tensor of the relativistic accretion ows in the Kerr metric, overall and without any approximation. We obtain the relations of all components of the relativistic bulk and shear tensor in terms of components of four-velocity and its derivatives, Christoffel symbols and metric components in the BLF. Then, these components are deri...
متن کاملActivation of LVGCCs and CB1 receptors required for destabilization of reactivated contextual fear memories.
Previous studies have shown that inhibiting protein synthesis shortly after reactivation impairs the subsequent expression of a previously consolidated fear memory. This has suggested that reactivation returns a memory to a labile state and that protein synthesis is required for the subsequent restabilization of memory. While the molecular mechanisms underlying the restabilization of reactivate...
متن کاملHarnessing Electric Fields for Microfluidics – From Lightning Sparks to Tiny Tornadoes
The dominance of surface tension and viscous effects over body forces such as inertia, gravity or centrifugal force makes fluid actuation and particle manipulation at microscale dimensions extremely difficult. We demonstrate the possibility of exploiting electric fields to drive unstable turbulent-like flows for micromixing and complex flows for efficient particle separation and concentration. ...
متن کاملAnalysis on Centrifugal Load Effect in FG Hollow Sphere Subjected to Magnetic Field
This paper presents the effect of centrifugal load in functionally graded (FG) hollow sphere subjected to uniform magnetic field. Analytical solution for stresses and perturbation of the magnetic field vector are determined using the direct method and the power series method. The material stiffness, the magnetic permeability and the density vary continuously across the thickness direction accor...
متن کاملGlobal Solutions of Viscous Transonic Flows in Kerr Geometry I: Weak Viscosity Limit
We present fully general relativistic equations governing viscous transonic flows in vertical equilibrium in Kerr geometry. We find the complete set of global solutions (both for Optically thick and optically thin flows) in the weak viscosity limit. We show that for a large region of parameter space, centrifugal pressure supported standing shocks can form in accretion and winds very close to th...
