Active feedback control of a wake flow via forced oscillations based on a reduced model
… a symmetric recirculation bubble of vortices at small Reynolds numbers. As Reynolds number increases, the bubble becomes unstable and develops into a Karman vortex street of alternating vortices. This instability is responsible for the occurrence of large amplitude oscillations in the lift and an …

Exploring and Envisioning Periodic Laminar Flow Around a Cylinder
It is well known that for small Reynolds numbers, flow around a cylinder is laminar and stable. For larger Reynolds numbers, although the flow regime remains laminar, the formation of complex periodic structures appear downstream. The cyclic nature of this periodic flow is well characterized by the …

Multiphase Hydrodynamics in Flotation Systems
… a nearly radial direction from the impeller for small Reynolds numbers and with a wider distribution for higher Reynolds numbers. The rise of a buoyant bubble and its interaction with a free liquid surface was experimentally investigated using Time-Resolved Digital Particle Image Velocimetry as a …

Exploring plastron stability and fluid friction reduction on robust micro-textured non-wetting surfaces
… can potentially reduce skin friction drag. At small Reynolds numbers Re << 1, the effective Navier slip length is evaluated using torque measurements in a parallel plate rheometer resulting in a measured Navier slip length in laminar flow of b ~~ 39 [mu]m, comparable to the mean periodicity of …
