Description: A classic, and simple, problem in viscous, laminar flow involves the steady-state velocity and pressure distributions for a fluid moving laterally between two plates whose length and width is much greater than the distance separating them. Couette flow is frequently used in undergraduate physics and engineering courses to illustrate shear-driven fluid motion. A simple configuration corresponds to two infinite, parallel plates separated by a distance ; one plate translates with a constant relative velocity in its own plane.
