COUETTE FLOW Meaning and
Definition
-
Couette flow is a term in fluid dynamics that describes a type of laminar flow between two parallel plates where one plate is stationary, and the other plate is in motion relative to it, resulting in the movement of the fluid between the plates. It is named after Maurice Marie Alfred Couette, a French physicist who first studied this flow pattern.
In couette flow, the fluid motion occurs in layers parallel to the plates, with the top layers moving faster than the lower layers due to the difference in velocity between the plates. This flow pattern is typically observed in viscometers and rheometers, where it is essential to measure the viscosity or flow behavior of a fluid.
The movement of the fluid in couette flow is governed by the principles of viscous flow and shear stress. The shear stress is highest at the surface of the plates and decreases towards the center of the fluid layer. The shear stress causes a velocity gradient in the fluid, leading to the formation of velocity profiles, typically linear with respect to the distance from the stationary plate.
The velocity of the fluid in couette flow can be calculated using the principles of linear velocity distribution. The flow is characterized by a well-defined flow rate, shear rate, and pressure drop, which can be used to determine the viscosity and flow behavior of the fluid.
Couette flow is an important flow pattern studied in fluid mechanics and has applications in various fields such as chemical engineering, geophysics, and materials science. It provides valuable insights into the behavior of fluids and their interaction with solid boundaries.

Etymology of COUETTE FLOW
The word "couette flow" has a relatively straightforward etymology. The term "couette" comes from the French mathematician Maurice Couette (1858-1943), who first studied this type of fluid flow in the late 19th century. Couette flow refers to the motion of a viscous fluid confined between two parallel plates, with one plate moving while the other remains stationary. This flow configuration is commonly used in fluid dynamics experiments and serves as a fundamental model for analyzing fluid behavior under shear stress.
