Fluid-Structure Interaction Modeling for an Optimized Design of a Piezoelectric Energy Harvesting MEMS Generator

I. Kuehne[1], A. van der Linden[2], J. Seidel[1], M. Schreiter[1], L. Fromme[2], and A. Frey[1]
[1]Siemens AG, Corporate Research & Technologies, Munich, Germany
[2]Comsol Multiphysics GmbH, Göttingen, Germany

This paper reports the design of a piezoelectric energy harvesting micro generator for an energy autonomous tire pressure monitoring wireless sensor node. For our design we use a piezoelectric MEMS generator approach without additional mass. The intrinsic mass of the cantilever is in the ... Per saperne di più

Using Optical Flow Tracing of MRI Flow Artifacts to Validate CFD Findings

R. H. Lauridsen, S. Ringgaard, and S. Alberg Thrysøe
MR-Center
Aarhus University Hospital
Aarhus, Denmark

The aim of this study is to use tracking of flow artifacts in Magnetic Resonance Imaging of fluids to validate CFD. Phase Contrast MRI will also be used for comparison. The correlation between flow of the fluid and movement of the artifacts is investigated using an aorta flow phantom, ... Per saperne di più

Modelling and Simulation of Simultaneous Intrinsic Kinetics, Hydrogen Transport and Heat Transfer in Complex Hydride Hydrogen Storage Systems

G. A. Lozano, J. M. Bellosta von Colbe, T. Klassen, and M. Dornheim
Institute of Materials Research
Materials Technology
Helmholzt-Zentrum Geesthacht
Geesthacht, Germany

In proper designs of hydrogen storage systems based on metal hydrides three processes are modelled and simulated: hydrogen flow (through the metal hydride bed), solid-state chemical transformation, and heat transfer (due to the highly exothermic chemical transformation). In this work, ... Per saperne di più

Thermo-Fluidic Impulse Response and TOF Analysis of a Pulsed Hot Wire

O. Ecin, M. Malek, B. J. Hosticka, and A. Grabmaier
Chair for Electronic Components and Circuits
University of Duisburg-Esse
Duisburg, Germany

In this work the authors report on a CFD simulation of a pipe flow model. Fluid mechanics are here combined with heat transfer phenomena. To create a mathematical model of a pulsed hot wire system i.e., the thermo-fluidic impulse response of a pulsed hot wire, a simulation model is going ... Per saperne di più

Design of Electrochemical Machining Processes by Multiphysics Simulation

M. Hackert-Oschätzchen, S. F. Jahn, and A. Schubert
Chemnitz University of Technology
Chemnitz, Germany

The principle of electrochemical machining (ECM) is the anodic dissolution of a metallic workpiece at the interface to a liquid ionic conductor under the influence of electric charge transport. This erosion principle works independently from the mechanical hardness of the workpiece and ... Per saperne di più

The Effect of the Dispersion Term on Flux of a Fluid in Permeable Media

O. Toscanelli, and V. Colla
Scuola Superiore S. Anna
Pontedera, Italy

The flux of a fluid in permeable media can be modelled using a continuous. To link the real system with the continuous model is mandatory to realize a suitable average of the equations and of the variables. The dispersion term comes from this averaging but it is not only a mathematical ... Per saperne di più

Multiphysics Simulation of an Anode-supported Micro-tubular Solid Oxide Fuel Cell (SOFC)

G. Ganzer, W. Beckert, T. Pfeifer, and A. Michaelis
Fraunhofer IKTS
Dresden, Germany

The high thermal stability and fast start-up behavior make micro-tubular solid oxide fuel cells (SOFCs) a promising alternative for small-scale, mobile power devices in the range of some Watts. To understand the transport phenomena inside a single micro-tubular SOFC, a 2-D, axi ... Per saperne di più

[1]University Stuttgart, Institute for Interfacial Engineering, Stuttgart, Germany
[2]Fraunhofer-Institute for Interfacial Engineering and Biotechnology (IGB), Stuttgart, Germany

For the development of bioreactor systems, it is reasonable to develop working simulations, to avoid a lot \"trial-and-error\" experiments. Our research goal is the creation of functioning bone grafts for transplantation. Therefore stem cells get homogenously seeded into porous ceramic ... Per saperne di più
