Theoretical and experimental investigations of turbulent flows with separation
Abstract
Theoretical and experimental studies are reported on a turbulent flow in a two-dimensional channel of aspect ratio 1:16 in which a square obstacle of half the channel height was located. A one dimensional laser Doppler anemometer was used to measure the mean longitudinal velocity distribution and the rms values of the longitudinal velocity fluctuations. The measurements were carried out along the channel center from 20 channel heights upstream of the obstacle up to 33 channel heights downstream. The governing partial differential equations were solved numerically and results are described in the theoretical part of the paper.
