A Taylor Couette flow describes the fluid behavior between 2 concentric cylinders in rotation.
2.
It is an example of Couette flow.
3.
Actual co-axial cylinder devices used to create Couette flows have both curvature and finite geometry.
4.
Couette flow is frequently used in undergraduate physics and engineering courses to illustrate shear-driven fluid motion.
5.
On the other hand, the spectrum of eigenvalues for Couette flow indicates stability, at all Reynolds numbers.
6.
For Couette flow, it is possible to make mathematical progress in the solution of the Orr Sommerfeld equation.
7.
For example, in the case of cylindrical Couette flow with positive Rayleigh discriminant, there are no axisymmetric instabilities.
8.
The typical context of the Taylor number is in characterization of the Couette flow between rotating colinear cylinders or rotating concentric spheres.
9.
According to this classification the Taylor Couette flow is an example of a flow pattern forming in a closed, bounded flow system.
10.
Couette Flow ), the vorticity will be diffused throughout the flow field and it is probably simpler to look at the velocity field than at the vorticity.
