Gaseous Flows and Heat Transfer through Micro- and Nano-channels
The overall object of this paper is a systematic study of gaseous flows and thermal transport in twodimensional microand nano-channels using direct simulation Monte Carlo (DSMC) method. In the flow study, a validation of DSMC code was conducted by simulating a continuum flow in microchannel and the results show that the discrepancy of friction coefficient from theoretical prediction is well bel...
متن کاملDesign principle for improved three-dimensional ac electro-osmotic pumps.
Three-dimensional (3D) ac electro-osmotic (ACEO) pumps have recently been developed that are much faster and more robust than previous planar designs. The basic idea is to create a "fluid conveyor belt" by placing opposing ACEO slip velocities at different heights. Current designs involve electrodes with electroplated steps, whose heights have been optimized in simulations and experiments. Here...
متن کاملTheoretical prediction of fast 3D AC electro-osmotic pumps.
AC electro-osmotic (ACEO) pumps in microfluidics currently involve planar electrode arrays, but recent work on the underlying phenomenon of induced-charge electro-osmosis (ICEO) suggests that three-dimensional (3D) geometries may be exploited to achieve faster flows. In this paper, we present some new design principles for periodic 3D ACEO pumps, such as the "fluid conveyor belt" of ICEO flow o...

متن کاملAn electro-osmotic micro-pump based on monolithic silica for micro-flow analyses and electro-sprays.
A high-pressure electro-osmotic micro-pump fabricated by a sol-gel process is reported as a fluid-driving unit in a flow-injection analysis (FIA) system. The micro FIA system consists of a monolithic micro-pump on a glass slide (2.5 x 7.5 cm), a micro-injector, and a micro-sensor (2.5 x 1.5 cm). The monolithic silica matrix has a continuous skeleton morphology with micrometer-sized through-pore...
