System Model for a Novel No Moving Parts Diffuser Valve Based Diaphragm Actuated Micro Pump

Banerjee D., Yano K., Bart S.F., Coventor, US

Analytical results for oscillating flow in a channel indicate regions of high shear stress close to the wall along with the flow reversal in the central portion of the flow at certain frequencies of actuation. [...]

Development of Patterned SMA Strips as Self-Heating Resistors

Chen J., Cheng X.L., Cai B.C., Xu D., Wang L., Cheng X.L., Shanghai Jiao Tong University, SG

A way to develop the pattern of shape memory alloys (SMA) titanium-nickel (TiNi) strips for improving the actuation performance of membrane microactuator is described in this paper. The patterned SMA strips serve not only as [...]

Dynamic Analysis of an Electrostatic Micropump

Jiang T.Y., Ng T.Y., Lam K.Y., National University of Singapore, SG

In this paper, a micropump actuated by electrostatic force is dynamically analysed. Mathematical model is established to evaluate the dynamic response of the micropump. Electro-mechanical coupling effect is considered in evaluating the electrostatic force applied [...]

Modeling Strategies for Microsystems

Voigt P., Schrag G., König E-R, Wachutka G., Technical University of Münich, DE

A hierarchical approach to microsystem modeling is outlined. On the device level, the operating behavior is analyzed on the basis of continuous field models To deal with the coupling effects typical of microsystems, various coupling [...]

Modeling and Design Optimization of a Novel Micropump

Klein A., Matsumoto S., Gerlach G., Dresden University of Technology, DE

The purpose of this paper is to give an overview about the design process of a new-type micropump. Four different coupled physical domains must be considered. The coupling effects on the pysical level are modeled [...]

Unsteady Gaseous Flows in Tapered Microchannels

Aubert C., Colin S., Caen R., Laboratoire de Genie Mecanique de Toulouse, FR

The aim of the paper is to contribute to the modeling of unsteady slip flows in rectangular microchannels with slowly varying cross-sections. A model is proposed for a microdiffuser submitted to sinusoidal pressure fluctuations at [...]
