Abstract
The flow of a newtonian viscous fluid through a cylindrical duct in the vicinity of a section discontinuity is studied using a visualization technique.
The evolution with the Reynolds number of the features of the stationary vortex cell is given, in particular the reversibility of the flow is verified for the very small Reynolds numbers. In the creeping regime a detailed analysis of the velocity and strain-rate fields is performed.
