Couette Flow with Plane Fixed Wall

Direct Numerical Simulations by Kuroda et al.

Flow Description

Flow in a channel, between a plane fixed wall and a plane moving wall. The distance between the two walls is 2.

Flow Characteristics

Re = U_w/ = 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.

Flow Parameters

Air with a kinematic viscosity: = 1.5 × 10^-5 m²/s.
Wall velocity: U_w.
Flow rate velocity: U_q.
Friction velocity on fixed wall:
Friction velocity on moving wall:
Non-dimensional pressure gradient: a = (/U_w²) p/x = -1.33 × 10^-3
