Topics: Transition, Turbulence, Turbulence models, Visualization techniques
These videos show visualization of the flow structure evolution behind the semicylindrical rib in the channel at different stages of transition to turbulence. It is shown that starting from a certain Reynolds number, large-scale vortices are generated in the mixing layer behind the smoothly shaped rib. The main stages of the shear layer stability loss and vortex generation are observed.
