Abstract
Velocities have been measured with laser Doppler anemometry
between tubes in cross-flow in a small in-line tube bundle with
longitudinal to transverse pitches of 1.5Dx1.8D and a Reynolds
number based on mean velocity in minimum flow section of Re=30000.
At most locations a single recirculation zone is found behind each
tube. However, the direction of circulation changes sign along the
tube with a period of about 2~tube diameters. Three different
patterns of such recirculation zones have been observed. Each
pattern is very stable and does not change under undisturbed flow
conditions.
