Control of Real Distributed Parameter Systems Modeled by COMSOL Multiphysics® Software

C. Belavý[1], G. Hulkó[1], S. Lipár[1], B. Barbolyas[1]
[1]Institute of Automation, Measurement and Applied Informatics, Faculty of Mechanical Engineering, Slovak University of Technology in Bratislava, Bratislava, Slovak Republic

In the paper, first a basic concept of the engineering approach for modeling and control of distributed parameter systems (DPS) based on interpretation of controlled systems as lumped input and distributed output systems (LDS) is introduced. Next, FEM modeling of temperature fields in ... En savoir plus

Wavebased Micromotor for Plane Motions (3-DoF)

G. Jehle, D. Kern, and W. Seemann
Karlsruhe Institute of Technology (KIT), Karlsruhe, Germany

This paper proposes the design of a 3-Degree of Freedom(DoF) motor based on surface acoustic waves in elastic solids. The rotor is propelled by wave fields, for linear and rotational motion respectively, in the stator, that can be steered by the driving signal of the piezoelectric ... En savoir plus

Design of Passive Micromixers using the COMSOL Multiphysics software package

M. Itomlenskis, P. Fodor, and M. Kaufman

Physics Department, Cleveland State University, Cleveland, OH, USA

Relief patterning of the surface of microchannels has been actively pursued as a method of promoting mixing in systems with a low Reynold’s number (<<100). In this work, we explore, by using the COMSOL Multiphysics package and its Chemical Engineering Module, the possibility of ... En savoir plus

Energy Harvesting from Variation in Blood Pressure through Deformation of Arterial Wall using Electro-magneto-hydrodynamics

A. Pfenniger[1], V.M. Koch[2], A. Stahel[2], and R. Vogel[1]
[1]ARTORG Cardiovascular Engineering, University of Bern, Bern, Switzerland
[2]Bern University of Applied Sciences, Engineering and Information Technology, Biel, Switzerland

The present project aims at modelling a generator that harvests energy from the variation in blood pressure by exploiting the motion of the arterial wall between the diastolic and systolic phase of the cardiac cycle. The concept is to use a highly electrically conductive fluid, which is ... En savoir plus

Helium Two-Phase Flow in a Thermosiphon Open Loop

B. Baudouy[1] and F. Visentin[1]
[1]CEA, Irfu, SACM, Gif-sur-Yvette, France

The construction of high magnetic field superconducting coils requires the use of low temperature superconductors that must be cooled down to liquid helium temperature (4.2 K). Natural two-phase convection loops, i.e. thermosiphon loop, are used as cooling system for large ... En savoir plus

Geometric Modeling and Numerical Simulation of Airfoil Shapes Using Integrated MATLAB® and COMSOL Multiphysics

A. Safari[1], H. Lemu G.[1], H. Severson[1]
[1]University of Stavanger, Stavanger, Norway

This paper proposes a framework for an efficient integration between geometric modeling program and analysis tool for a coming automated aerodynamic design optimization mission. This demand can be addressed by using both in-house codes and commercial software which have the good ability ... En savoir plus

Two Step Study of Flow in an Industrial Pulp Screen, Solved with the COMSOL Multiphysics® Mixer Module

R. Wetind[1]
[1]Wetind Technology AB, Alnö, Sweden

An industrial pulp screen is investigated. The dilute pulp is pumped through a screen barrier. In order to avoid the fiber network to plug, it is necessary to 1) fluidize the shear thinning pulp 2) expose the barrier with plug releasing pressure pulses. This work involves a 2-step ...

Optimization of Product from a Segregated Reactor via a Hybrid Modeling Approach

E. Akgün [1], V. Souza [1], J. Appel [1]
Clariant Produkte (Deutschland) GmbH, Burgkirchen, Germany

In the field of chemical reaction engineering chemical kinetics and fluid dynamics are described by various mathematical approaches. Such tools help to shorten the time-to-market of novel products and processes. Thanks to the continuously improving computation power, it is possible to ... En savoir plus

Multiphysics Process Simulation of the Electromagnetic-Supported Laser Beam Welding

M. Bachmann, V. Avilov, A. Gumenyuk, and M. Rethmeier
BAM Federal Institute for Materials Research and Testing
Berlin, Germany

The article deals with the magnetically-supported high-power full-penetration laser beam welding of aluminum. A stationary simulation was conducted accounting for the effects of natural convection, Marangoni convection and solid-liquid phase transition as well as an electromagnetic ... En savoir plus

The Use of CFD Simulations in Learning Fluid Mechanics at the Undergraduate Level

Marc K. Smith
Professor of Mechanical Engineering, Georgia Institute of Technology

Simple, accurate CFD simulations using COMSOL Multiphysics are used in a senior-level undergraduate course as a means to explore a number of fluid flows with the intent of developing a deep understanding of the underlying fluid mechanical mechanisms involved in the flows. Students also ... En savoir plus
