Anomalous Transport of Elongated Particles in Oscillatory Vortical Flows
Shiyuan Hu, Xiuyuan Yang, Nan Luo +2
We investigate the transport dynamics of elongated particles in cellular vortical flows that undergo spatial oscillations over time. Experimental flow visualizations reveal mixed f…
Enhanced clamshell swimming with asymmetric beating at low Reynolds number
Shiyuan Hu, Jun Zhang, Michael J. Shelley
A single flexible filament can be actuated to escape from the scallop theorem and generate net propulsion at low Reynolds number. In this work, we study the dynamics of a simple bo…
Locomotion of C. elegans in Structured Environments
Trushant S. Majmudar, Eric Keaveny, Mike Shelley +1
Undulatory locomotion of microorganisms like soil-dwelling worms and spermatozoa, in structured environments, is ubiquitous in nature. They navigate complex environments consisting…
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…
Surface Waves on a Semi-toroidal Water Ring
Sunghwan Jung, Erica Kim, Michael Shelley +1
We study the dynamics of surface waves on a semi-toroidal ring of water that is excited by vertical vibration. We create this specific fluid volume by patterning a glass plate with…
