Dynamically forced cells of a viscoelastic fluid over an array of rollers
Bin Liu, Jun Zhang, Michael Shelley
Our fluid dynamics video shows the response of a layer of viscoelastic fluid to an array of four-roll mills steadily rotating underneath. When the relaxation time of the fluid is s…

Vortex shedding and hovering of a rigid body in an oscillating flow
Bin Liu, Annie Weathers, Stephen Childress +1
The fluid dynamics video shows rigid, spatially asymmetric bodies interacting with oscillating background flows. A free rigid object, here a hollow "pyramid," can hover quite stabl…
