摘要:

Measurements of mean velocity and turbulence intensity in various cross‐stream planes in a 90° square duct of 1.5 radius ratio for the Reynolds number of 4.7 × 104are presented. The bend was preceded by a short upstream tangent with air as flowing fluid. The technique used was laser‐Doppler velocimetry.
