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.
