Adaptive Control of Simulated Moving Bed Plants Using Comsol’s Simulink Interface

M. Fütterer
Institut für Automatisierungstechnik, Otto-von-Guericke Universität, Magdeburg, Germany

Preparative chromatography is an important separation method where the simulated moving bed (SMB) technology is an increasingly used separation process for binary mixtures. Several chromatographic columns are arranged in a ring where the feedings and drains are changed cyclically to ... Read More

Determination of Process Parameters for Electron Beam Sintering (EBS)

M. F. Zäh, S. Lutzmann, M. Kahnert, and F. Walchshäusl
iwb Anwenderzentrum Augsburg, TU München, Augsburg, Germany

Additive Layer Manufacturing (ALM) methods, like Electron Beam Sintering (EBS), constitute an interesting process concerning the production of small series and customized products. However, transient effects occur during processing due to the different physical principles of an electron ... Read More

Modeling of Respiratory Lung Motion as a Contact Problem of Elasticity Theory

R. Werner, J. Ehrhardt, and H. Handels
University Medical Center Hamburg-Eppendorf, Germany

Breathing motion is a major problem in radiotherapy of lung tumors. The development of techniques to adequately account for respiratory motion requires detailed knowledge about breathing dynamics. Thus, computer aided modeling of respiratory motion gains in importance. In this paper we ... Read More

Design of an Electrodynamically Actuated Microvalve Using COMSOL Multiphysics® and MATLAB®

M. Williams, J. Zito, J. Agashe, A. Sopeju, and D. Arnold
University of Florida, Gainesville, USA

This paper describes the design of a normally closed, electrodynamic microvalve.  Magnetic forces between a permanent magnet in the valve cover and a soft magnet in the valve seat hold the valve closed.  The combination of electrodynamic actuation and a mechanical restoring spring are ...

Optimization of an Electromagnetic Actuator with COMSOL Multiphysics

T. Müller[1], A. Schwenger[2], and H. Haase[1]
[1]Institut für Grundlagen der Elektrotechnik und Messtechnik, Leibniz Universität Hannover, Germany
[2]Volkswagen AG, Germany

This paper describes the automatic optimization of an electromagnetic actuator using a genetic algorithm.  The actuator modeled here is dedicated for charge changing valve actuation in internal combustion engines. In the first step of the simulation, several operating points are ... Read More

Modeling Dispersal of Genetic Information in Structured Agricultural Landscapes with Partial Differential Equations

K. Lipsius, and O. Richter
Institute of Geoecology, TU Braunschweig, Germany

We present a model for plant dispersal in agricultural landscapes to evaluate the gene dispersal from genetically modified (GM) plants. Dispersal from seed and pollen is modeled with partial differential equations. In scenarios, we investigated the effect of roadside application of non ... Read More

Magnetic Ratchet

A. Auge, F. Wittbracht, A. Weddemann, and A. Hütten
Department of Physics, University of Bielefeld, Germany

Transport phenomena in spatially periodic magnetic systems, in particular the directed transport of magnetic beads in a so called magnetic ratchet (Brownian motor) are considered. Simulations are carried out to test and optimize this system, where the Smoluchowski equation with flux ... Read More

Design and Simulation of an Electromagnetic Valve Actuator Using COMSOL Multiphysics

R. Wislati , H. Haase
Leibniz Universität Hannover, Germany

In this paper an electromagnetic solenoid actuator (EMVA) consisting of an upper and lower electromagnet, a linear moving armature and two preloaded springs is considered as a potential approach in Variable Valve Actuation (VVA) Systems for Internal Combustion Engines. In opposition to ... Read More

Implementation of the Finite Isotropic Linear Cosserat Models based on the Weak Form

J. Jeong[1], and H. Ramezani[2]
[1]Ecole Speciale des Travaux Publics du Batiment et del’Industrie(ESTP), Cachan, France
[2]Ecole Polytechnique de l’Universite d’Orleans CNRS/CRMD, Orleans, France

The Cosserat models fall into the group of the extended continuum media. They are capable of treating the size effects (characteristic length) in a natural manner using six material moduli for the isotropic elastic cases instead of two (and) for the classical continuum mechanics. This ... Read More

Coupled Fluid-Structural Analysis of Heart Mitral Valve

A. Avanzini, and G. Donzella
Department of Mechanical and Industrial Engineering, University of Brescia, Brescia, Italy

The mitral valve apparatus is a complex and refined mechanism located between the left atrium and the left ventricle of the heart which can manifest various kinds of pathologies. In order to support identification of potentially critical conditions resulting from some typical ... Read More
