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. Neglecting pressure gradients, the Navier–Stokes equations simplify to
WebDistance between plates L=0.01[m] Reynolds number Re = V*L/ν=50*0.01/1.510e-5 = 33104. Results. The distribution of the fluid velocities is shown below. A graph below is given by selecting [Graph on … WebIn Figure 2.2, laminar flow takes place between two stationary parallel plates separated by a thin film. Flow is caused by the application of pressure at one end. The flow is resisted by shear stresses in the fluid. The velocity at the boundary is zero and increases to a maximum at the center of the thin film.
WebJul 20, 2024 · He was able to characterize the transition between these two types of flow by a parameter called the Reynolds number that depends on the average velocity of the … WebThe net volume flux (per unit width in the -direction) of fluid between the plates is. (10.9) Note that this flux is directly proportional to the effective pressure gradient, inversely …
For a fluid moving between two plane parallel surfaces—where the width is much greater than the space between the plates—then the characteristic dimension is equal to the distance between the plates. This is consistent with the annular duct and rectangular duct cases above, taken to a limiting aspect ratio.
