Microflows with Moving Boundaries: Experiment and Simulation

Maier C., Hofer E.P., University of Ulm, DE

Surface forces and capillary effects can play a dominant role in fluidic microsystems. Therefore it is crucial for simulations to use accurate numerical approaches [1]. Furthermore experimental data gained from such surface dominated systems can [...]

Use of Numerical Methods for Modeling and Simulating Capillary Driven Flows in Microchannels

Quinte A., Halstenberg S., Eggert H., Forschungszentrum Karlsruhe, DE

Today, medical test strips are used for rapid diagnostics and the quick and easy determination of biomedically relevant parameters, such as the content of glucose of the blood. For the transport of the test uid [...]

A Mathematical Model of a Biosensor

Botkin N.D., Schlensog M., Tewes M., Turova V.L., Center of Advanced European Studies and Research, DE

A mathematical model of a biosensor is considered. The biosensor is supposed to be used for the measurement of small amounts of certain substances in liquids. The device works as follows: acoustic shear waves are [...]

Simulation of Droplet Formation in Micromixers

Hardt S., Schönfeld F., Weise F., Hofmann C., Ehrfeld W., Institut für Mikrotechnik, DE

Droplet formation in micromixers developed by the Institute of Microtechnology Mainz (IMM) is investigated by methods of computational fluid dynamics (CFD). The CFD results are compared to experimental data obtained with transparent micromixers made from [...]

Efficient Numerical Methods for the Simulation of Flow Reactors

Becker R., Braack M., Heuveline V., Rannacher R., University of Heidelberg, DE

We describe recent developments in the design of numerical methods for the simulation of heat transport and chemical processes in ow reactors. For viscous ow in the low-Mach-number regime, we use a stable finite element [...]

Microsystem Model Evaluation Using Optimization Strategies

Peters D., Laur R., University of Bremen, DE

This paper presents an automatic approach for evaluating behavioral models of micro systems' components. Optimization methods are applied aiming at the specification of a model's scope of application. The method is presented by evaluating a [...]

Optimization of Integrated Magnetic Field Sensors

Lienemann J., Greiner A., Korvink J.G., Sigmund O., Albert Ludwig University, DE

We present an optimization strategy for the offset reduction of integrated magnetic field sensors with simultaneous maximization of sensitivity. We use the topology optimization method to automatically find a design with maximal sensitivity for given [...]
