Couette Flow with Plane Fixed Wall
Direct Numerical Simulations by Kuroda et al.
Flow in a channel, between a plane fixed wall and a plane moving wall. The distance
between the two walls is 2.
Re = Uw/ = 3000
DNS data are available for the developed flow of "intermediate type".
U/y = 0
close to the moving wall (U does not follow the logarithmic law of the wall) is the main feature of the developed flow.
Air with a kinematic viscosity:
= 1.5 × 10-5 m2/s.
Wall velocity: Uw.
Flow rate velocity: Uq.
Friction velocity on fixed wall:
Friction velocity on moving wall:
Non-dimensional pressure gradient:
a = (/Uw2)
= -1.33 × 10-3
