Adaptive Control of Simulated Moving Bed Plants Using Comsol’s Simulink Interface
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)
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
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®
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 ... Read More
Optimization of an Electromagnetic Actuator with COMSOL Multiphysics
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
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
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
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
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
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
