Design, Fabrication and Experimental-Numerical Study of PZT Sensors

Arik M., Zurnx S.M., Yigit K.S., Bar-Cohen A., University of Minnesota, US

MEMS micropumps, based on PZT membranes have been designed and fabricated at the Microtechnology Laboratory of the University of Minnesota for use in fluid flow control, and as chemical and pressure sensors. Design, fabrication and [...]

Data on the Slip Coefficients

Sharipov F., Universidade Federal do Parana, BR

For mathematical modeling of micro fluidics it is necessary to calculate a rarefied gas ow through micropumps, microvalves and other elements with a high accuracy. Since the size of micro fluidics is close to the [...]

Application of the Gaseous Cross Phenomena to Microfluidics

Sharipov F., Universidade Federal do Parana, BR

Since the size of micro fluidics is very small the gas owing through micropumps, microvalves etc. can not be considered as a continuous medium but its rarefacation must be taken into account. The rarefied gas [...]

Theoretical Approximations for the Average Linear Flow of Carrier Gas Through a Rectangular GC Column

Spangler G.E., Technispan LLC, US

The ability of a gas chromatographic (GC) column to separate two compounds is determined by its analytical resolution. The height equivalent to a theoretical plate (HETP) is given by Eq. 1. For a rectangular column, [...]

Pneumatic Regulation of Bi-Directional Fluid Flow in Microchannels

Wan Y-M., Wang S-H., Yao N-K., Chen C., Hung L-Y., Wang S-H., ITRI, TW

This paper presents a modeling of airflow inside micro-tunnel for fluid pumping. By utilizing unidirectional air servo system, fluid flow can be regulated within microchannels. The operation of servo system is controlled with multiple nozzles. [...]

Hierarchical Simulation for Microelectrofluidic System Performance Analysis

Zhang T., Dewey A., Duke University, US

With the sophisticated development of microelectro fluiidic devices and systems, system performance analysis is a key for system optimization and system re-design. Due to the increasing complexity and natural characteristics of microsystems, system performance is [...]

A Study on the Fluid-Structure Interaction using LSFEM

Lee S-H., Youn S-K., Yeon J-H., Jiang B-N., KAIST, KR

A study on the fluid-structure interaction using LSFEM is presented. To consider fluid-structure interaction, staggered scheme, which solves fluid and structure respectively by separate solvers in a predictor-corrector fashion, is used. To analyze fluid-structure interaction [...]
