Couette flow tests were performed on these three formulations at different solid volume fractions ranging between 45% and 66.
A heat transfer correlation based on turbulent Couette flow was developed to better predict heat transfer losses in Wankel rotary engines [8].
Within the downstream gap there is a superposition of the web-driven Couette flow and the pressure-induced Poiseuille flow.
The unsteady Couette flow problem has been considered in several works containing various effects.
Chauhan and Rastogi [9, 10] have considered Hall current and heat transfer effects on MHD flow and MHD Couette flow in a channel partially filled with a porous medium in a rotating system.
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].
Transciet couette flow in a rotating non-Darcian porous medium parallel plate configuration is studied by Anwarbeg et al.
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.
