What are the characteristics of Couette flow between two parallel plates?

Couette flow between two parallel plates is a type of fluid flow where the fluid moves in a steady, linear manner between the plates. The flow is characterized by a constant velocity gradient in the direction perpendicular to the plates, with the velocity of the fluid increasing linearly from one plate to the other. This type of flow is often used in engineering applications to study the behavior of viscous fluids under shear stress.
