Passive control of viscous flow via elastic snap-through

M Gomez, DE Moulton, D Vella - Physical review letters, 2017 - APS
We demonstrate the passive control of viscous flow in a channel by using an elastic arch
embedded in the flow. Depending on the fluid flux, the arch may “snap” between two states …
