On the inflation and deflation dynamics of liquid-filled, hyperelastic balloons
Dotan Ilssar, Amir D. Gat
We derive a reduced-order model describing the inflation and deflation dynamics of a liquid-filled hyperelastic balloon, focusing on inviscid laminar flow and the extensional motio…
Leveraging viscous peeling in soft actuators and reconfigurable microchannel networks
Lior Salem, Benny Gamus, Yizhar Or +1
The research fields of microfluidics and soft robotics both involve complex small-scale internal channel networks, embedded within a solid structure. This work examines leveraging…
Non-uniform electro-osmotic flow drives fluid-structure instability
Evgeniy Boyko, Ran Eshel, Amir D. Gat +1
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…
Viscous-elastic dynamics of power-law fluids within an elastic cylinder
Evgeniy Boyko, Moran Bercovici, Amir D. Gat
In a wide range of applications, microfluidic channels are implemented in soft substrates. In such configurations, where fluidic inertia and compressibility are negligible, the pro…
Dynamics and instabilities of an arbitrarily clamped elastic sheet in potential flow with application to shape-morphing airfoils
Netanel Hassan, Shai B. Elbaz, Amir D. Gat
The aim of this work is to study the dynamics and stability of soft shape-morphing configurations and specifically the modes of interaction between the front and rear airfoil segme…
Gaseous viscous peeling of linearly elastic substrates
Shai B. Elbaz, Hila Jacob, Amir D. Gat
We study pressure-driven propagation of gas into a micron-scale gap between two linearly elastic substrates. Applying the lubrication approximation, the flow-field is governed by t…
