Nonuniform Electro-osmotic Flow Drives Fluid-Structure Instability
Nonuniform Electro-osmotic Flow Drives Fluid-Structure Instability
We demonstrate the existence of a fluid-structure instability arising from the interaction of electro-osmotic flow with an elastic substrate. Considering the case of flow within a soft fluidic chamber, we show that above a certain electric field threshold, negative gauge pressure induced by electro-osmotic flow causes the collapse of its …
