Parameter Preserving Model Order Reduction of a Flow Meter

Moosmann C., Rudnyi E.B., Greiner A., Korvink J.G., Hornung M., IMTEK, University of Freiburg, DE

Model order reduction is known to work reliably for MEMS simulations and can beused to speed up transient and harmonic computations tremendously. However, using standard model reduction techniques the generated reduced models are only able [...]

Simulation Toolkit for Micro-Fluidic Pumps using Lumped Models

Litterst C., Streule W., Zengerle R., Koltay P., IMTEK, University of Freiburg, DE

Simulation of micro pumps is complicated by the interaction of various physical domains. The fluid structure interaction (FSI) essentially determines the dynamics of micro pumps and therefore has to be taken into account. Mesh based [...]

The Model of Porous Media – Complete Description for Aggregation of Bead-Monolayers in Flat Microfluidic Chambers

Grumann M., Dobmeier M., Schippers P., Brenner T., Zengerle R., Ducrée J., IMTEK, University of Freiburg, DE

In this paper we for the first time adopt the model of porous media to simulate the complete course of the formation of monolayers from bead suspensions in a flat microfluidic chamber. The chambers are [...]

Krylov-Subspace-Based Order Reduction Methods Applied to Generate Compact Thermo-Electric Models for MEMS

Bechtold T., Salimbahrami B., Rudnyi E.B., Lohmann B., Korvink J.G., IMTEK, University of Freiburg, DE

A high power dissipation density in todays miniature electronic/mechanical systems makes on-chip thermal management very important. In order to achieve quick to evaluate, yet accurate thermo-electric models, needed for the thermal management of microsystems, a [...]
