Fluidic Shaping over arbitrary domains: theory and high order finite-elements solver
Amos A. Hari, Moran Bercovici
Fluidic Shaping is a novel method for fabrication of optical components based on the equilibrium state of liquid volumes in neutral buoyancy, subjected to geometrical constraints.…
Dynamics of fixed-volume pinned film -- dealing with a non-self-adjoint thin film problem
Israel Gabay, Vesna Bacheva, Dotan Ilssar +3
The use of thin liquid films has expanded beyond lubrication and coatings, and into applications in actuators and adaptive optical elements. In contrast to their predecessors, whos…
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…
Dipolar thermocapillary motor and swimmer
Valeri Frumkin, Moran Bercovici
We present a theoretical description and an experimental realization of a thermocapillary dipole induced in a Hele-Shaw cell under a steady temperature gradient. We demonstrate exp…
Elastohydrodynamics of a pre-stretched finite elastic sheet lubricated by a thin viscous film with application to microfluidic soft actuators
Evgeniy Boyko, Ran Eshel, Khaled Gommed +2
The interaction of a thin viscous film with an elastic sheet results in coupling of pressure and deformation, which can be utilized as an actuation mechanism for surface deformatio…
Induced Charge Capacitive Deionization: The electrokinetic response of a porous particle to an external electric field
S. Rubin, M. E. Suss, P. M. Biesheuvel +1
We demonstrate the phenomenon of induced-charge capacitive deionization (ICCDI) that occurs around a porous and conducting particle immersed in an electrolyte, under the action of…
Flow of Power-Law Liquids in a Hele-Shaw Cell Driven by Non-Uniform Electroosmotic Slip in the Case of Strong Depletion
Evgeniy Boyko, Moran Bercovici, Amir D. Gat
We analyze flow of non-Newtonian fluids in a Hele-Shaw cell, subjected to spatially non-uniform electroosmotic slip. Motivated by their potential use for increasing the characteris…
Elastic deformations driven by non-uniform lubrication flows
Shimon Rubin, Arie Tulchinsky, Amir Gat +1
The ability to create dynamic deformations of micron-sized structures is relevant to a wide variety of applications such as adaptable optics, soft robotics, and reconfigurable micr…
Electroosmotic flow in Hele-Shaw configurations with non-uniform surface charge
Evgeniy Boyko, Shimon Rubin, Amir D. Gat +1
We present an analytical study, validated by numerical simulations, of electroosmotic flow in a Hele-Shaw cell with non-uniform surface charge patterning. Applying the lubrication…
