Formation of Taylor Vortices in Spherical Couette Flow

چکیده
We have conducted a numerical studv of spherical Couette Vlow -the flow between differentiallv rotatin~ concentric spheres. When the qa D ratio o{(R2-RI)/RI (where R 1 and R 2 are the radii of the inner and outer spheres) is small, the flow near the e~uator resembles that between cylinders, the classic Tavlor-Couette ~roblem. As in Tavlor-Couette flow, when the angular momentum gradient, measured by the Reynolds number Re ~RI2QI/~ (where Q1 is the anaular velocitv of the inner sphere and v the kinetic viscosit}7) exceeds a critical value, Taylor vortices form to redistribute anaular momentum between radial shells.

Hydrodynamic Flow and Heat Transfer Characteristics of SCF
We study the fundamental problem of spherical Couette flow (SCF) in the presence of heat and under the action of a gravitational field. The flow is considered as unsteady, axisymmetric and the fluid as viscous, incompressible and Newtonian. The numerical technique, which we use, is convergent and consistent and can be applied to 3D or 2D flow motions. We focus our attention to such aspect ratio...
متن کاملSimulation of flow between concentric rotating spheres. Part 1. Steady states
Axisymmetric spherical Couette flow between two concentric differentially rotating spheres is computed numerically as an initial-value problem. The time-independent spherical Couette flows with zero, one and two Taylor vortices computed in our simulations are found to be reflection-symmetric about the equator despite the fact that our pseudospectral numerical method did not impose these propert...
متن کاملNonlinear Stability of Bifurcating Front Solutions for the Taylor- Couette Problem
We consider the Taylor-Couette problem in an infinitely extended cylindrical domain. There exist modulated front solutions which describe the spreading of the stable Taylor vortices into the region of the unstable Couette flow. These transient solutions have the form of a front-like envelope advancing in the laboratory frame and leaving behind the stationary, spatially periodic Taylor vortices....
متن کاملTransition from the Couette-Taylor system to the plane Couette system.
We discuss the flow between concentric rotating cylinders in the limit of large radii where the system approaches plane Couette flow. We discuss how in this limit the linear instability that leads to the formation of Taylor vortices is lost and how the character of the transition approaches that of planar shear flows. In particular, a parameter regime is identified where fractal distributions o...
متن کاملHydrodynamic stability of a suspension in cylindrical Couette flow
A linear stability analysis was carried out for a dilute suspension of rigid spherical particles in cylindrical Couette flow. The perturbation equations for both the continuous fluid phase and the discontinuous particle phase were decomposed into normal modes resulting in an eigenvalue problem that was solved numerically. At a given radius ratio, the theoretical critical Taylor number at which ...
