Topology and shape optimization of induced-charge electro-osmotic micropumps
For a dielectric solid surrounded by an electrolyte and positioned inside an externally biased parallel-plate capacitor, we study numerically how the resulting induced-charge electro-osmotic (ICEO) flow depends on the topology and shape of the dielectric solid. In particular, we extend existing conventional electrokinetic models with an artificial design field to describe the transition from th...
متن کاملPatterning electro-osmotic flow with patterned surface charge.
This Letter reports the measurement of electro-osmotic flows (EOF) in microchannels with surface charge patterned on the 200 microm scale. We have investigated two classes of patterns: (1) Those in which the surface charge varies along a direction perpendicular to the electric field used to drive the EOF; this type of pattern generates multidirectional flow along the direction of the field. (2)...
متن کاملExperimental Investigation of Induced - Charge Electro - Osmosis
We analyze the general phenomenon of induced-charge electro-osmosis (ICEO), nonlinear electroosmotic slip generated when an electric field acts on its own induced charge around a polarizable surface, in the context of microfluidics. Simple ICEO flows are first observed around a platinum wire in a polymer microchannel. While convenient for scaling analysis of resulting flows, this geometry prove...
متن کاملLow-Cost Optimization for Fast-Microfluidic-Mixer Shape Design
We give an unified formulation for deterministic and stochastic global optimization algorithms via initial and boundary value problems for different first and second order dynamic systems. The ensemble is applied to the design of a fast-micro-mixer. The aim is to optimize a given mixer shape in order to reduce its mixing time. The algorithms are compared from their complexity and optimization e...
متن کاملInduced - charge electro - osmosis By TODD
We describe the general phenomenon of ‘induced-charge electro-osmosis’ (ICEO) — the nonlinear electro-osmotic slip that occurs when an applied field acts on the ionic charge it induces around a polarizable surface. Motivated by a simple physical picture, we calculate ICEO flows around conducting cylinders in steady (DC), oscillatory (AC), and suddenly-applied electric fields. This picture, and ...
