In-Plane Micropump: Design Optimization

Sin J., Lee W.H., Stephanou H.E., RPI, US

This paper presents the fabrication, analysis and optimization of a novel monolithically fabricated diaphragm micropump, referred to as an in-plane micropump. Compared to previous technology, the micropump in this paper is fabricated to have all [...]

Clogging Pressures of Bubbles in Microchannel Contractions: Theory and Experiments

Jensen M.J., Wang X., Attinger D., Bruus H., Mikroelektronik Centret, DTU, DK

We present a theoretical, numerical, and experimental study of bubbles passing through a microchannel contraction. A certain pressure, the so-called clogging pressure, is needed to push a bubble through a microchannel contraction. We present the [...]

Capillary Passive Valve in Microfluidic System

Cho H., Kim H-Y, Kim T.S., Kang J.Y., Kim H-Y, Kim T.S., Microsystem Research Center, Korea Institute of Science and Technology, KR

This work reports the theoretical and experimental investigations of capillary bust valves to regulate liquid flow in microchannels. The theoretical analysis uses the Young-Laplace equation and geometrical considerations to predict the pressure at the edge [...]

Liquid Disintegration: Investigation of Physics by Simulation

Zeng J., Korsmeyer T., Coventor, Inc., US

Liquid disintegration includes the processes of formation of droplets and droplet fission. It is important in inkjet printing and in the miniaturization of biochemical analytical devices. This paper reports on an investigation of the mechanism [...]

Galilean Invariant Viscosity Term for an Athermal Integer Lattice Boltzmann Automaton in three Dimensions

Geier M.C., Greiner A., Korvink J.G., IMTEK, Albert Ludwigs University Freiburg im Breisgau, DE

The athermal lattice Boltzmann automata (LBA) are promising replacements for Navier Stokes solvers in computational fluid dynamics (CFD). They are inherently parallel, scale exactly linear with the number of computational elements and can be applied [...]

A Low Cost Polymer Based Piezo-Actuated Micropump for Drug Delivery System

Liu H., Tay A.A.O., Wan S.Y.M., Lim G.C., Institute of Materials Research & Engineering, SG

This paper presents the design, realization and simulation of a novel polymer based check-valve micropump actuated by piezoelectric disc. Comparing with silicon substrate, polymer materials have such advantages as flexibility, chemical and biological compatibility, 3D [...]
