Transciet couette flow in a rotating non-Darcian porous medium parallel plate configuration is studied by Anwarbeg et al.
The main conclusion, that beyond a critical value of the speed of rotation of the vortex superimposed on the Couette flow significantly increase the transfers between the walls [9].
al [3] studied the unsteady couette flow of a viscous incompressible fluid confined between parallel plates, rotating with an uniform angular velocity about an axis normal to the plates, here the flow was induced by the motion of the upper plate and the fluid and plates rotate in unison with the same angular velocity.
Since the epoxy film thickness (<1 mm) is much less than the pipe radius (>7 mm), it can be assumed to exhibit planar Couette flow so that the average velocity of the epoxy, [V.
The hydraulic loading is performed using an ex situ scour testing device that produces what are known as Couette flow conditions, using a moving belt in still water over riverbed cohesive soil samples.
46] From clearance volume to muffler 1 (1) Flow is designated as (1) isentropic flow of compressible ideal gas, (2) mixed plane Couette flow and Poiseuille flow, or (3) laminar viscous flow into the chamber and isentropic flow out of the chamber.
This can be attributed to the fact that in the orbiting case couette flow velocities in both radial and tangential direction are present.
Rajasekhara [8] has performed the experiments to study the laminar flow characteristics in a composite channel considering Poiseuille flow, Couette flow and free surface flow.
Yih (1967) used a long-wave perturbation analysis to show that two-layer, viscosity-stratified plane Poiseuille flow and plane Couette flow can be unstable for arbitrarily small Reynolds numbers.
