Abstract
Measurements with particle image velocimetry of the fully
developed flow of water in a pipe with a Reynolds number of 5370
are presented. The measurements are taken with a frame rate high
enough to capture the same flow structure on 2 or 3 frames. This
makes it possible to estimate advection velocities of the flow
structures and distances between the structures. Ejection andsweep
structures are identified and it is found that average advection
velocity for the structures corresponds the local mean velocity at
a distance of 0.15 diameter from the wall. It is also noted that
ejections tend to appear in groups.
