Simple shear flow between parallel plates
WebbThe capacitance of a basic capacitor, for example, consisting of two parallel, flat plates separated by a dielectric, may be calculated from the formula: C = ε × A d where ε is the permittivity of the dielectric, A is the area of overlap of the plates, and d is the distance between the plates. Webbhas a velocity U in its own plane (the other plate is at rest) as a result of the application of a shear stress, τ, and there is no pressure gradient in the fluid. In contrast in planar Poiseuille flow both plates are at rest and the flow is caused by a pressure gradient, dp/dx, in the direction, x, parallel to the plates.

WebbThe top plate moves at a velocity V0and there is a pressure drop in the x-direction, parallel to the plates. There is no velocity or pressure drop in the z-, or y-directions, yis normal to the plates. The effects of gravity are ignored and the flow is steady-state. Assume Newtonian behavior. WebbFor flow between two parallel fixed plates due to the pressure gradient, compute: (a) The wall shear stress, (b) The stream function, (c) The vorticity, (d) The velocity potential, (e) The average velocity. Answer: We have seen that flow between parallel plates (fixed) for incompressible, steady state flow is: =−() ℎ2 2𝜇 [1− 2 ℎ2]

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. WebbViscosity - a measure of the importance of friction in fluid flow. Consider, for example, simple shear between two plates: Consider a fluid in 2-D steady shear between two infinite plates, as shown in the sketch. The bottom plate is fixed, while the upper plate is moving at a steady speed of V.

Couette Flow BY VIRENDRA KUMAR PHD PURSUING (IIT DELHI) 2. Introduction In fluid dynamics, Couette flow is the laminar flow of a viscous fluid in the space between two parallel plates, one of which is moving relative to the other. The flow is driven by virtue of viscous drag force acting on the fluid and the applied pressure …
