Abstract

The annular flumes have been used to study the cohesive sediment transport and secondary flows. This research was carried out in an annular flume located at the hydraulics laboratory of Shahrekord University to study the flow and shear stress distribution. The results of velocity measurements by Acoustic Doppler Velocimeter (ADV) showed that the shear stress distribution at the flume cross section was almost uniform for the relative rotational speed of the upper ring to the flume equal to 1.1. It was also found that the flume velocity profile was in good agreement with logarithmic relationship.
