文摘The main objective of this article is to study both dynamic and structural transitions of the Taylor-Couette flow, by using the dynamic transition theory and geometric theory of incompressible flows developed recently by the authors.

In addition, it is also shown that the new transition states have the Taylor vortex type of flow structure, which is structurally stable.
