Relativistic Quantum Mechanics Applications Using the Time Independent Dirac Equation in COMSOL Multiphysics® Software

A. J. Kalinowski [1],
[1] Consultant, East Lyme, CT, USA

The paper illustrates the use of the COMSOL Multiphysics® software (via the “Coefficient-Form PDE” option) for obtaining the relativistic quantum mechanics wave function ψm(x,y,ω), m=1,4 as a solution to the time independent Dirac equations. Once having ψm(x,y,ω), it can be used to ... Mehr lesen

Numerical Modeling and Verification of Acoustic Streaming Induced by Ultrasonic Treatment

[1] Institute of Thermal and Fluid Engineering, University of Applied Sciences Northwestern Switzerland, Windisch, Switzerland
[2] Institute of Product and Production Engineering, University of Applied Sciences Northwestern Switzerland, Windisch, Switzerland

Acoustic streaming (AS) describes a physical phenomenon where an oscillating sound emitter induces a steady fluid motion. Metal processing industry applies this treatment for grain morphology adjustments during the solidification of metal. Improvement and further development of this ... Mehr lesen

Numerical Investigation of Power Deposition and Transport Phenomena in Helicon Plasma Sources

M. Magarotto [1], F. J. Bosi [1], P. de Carlo [1], M. Manente [1], F. Trezzolani [1], D. Pavarin [1], P. Alotto [2], D. Melazzi [1],
[1] CISAS "G.Colombo", University of Padova, Padova, Italy
[2] Department of Industrial Engineering, University of Padova, Padova, Italy

Standard approaches to reproduce the coupling of wave propagation and plasma transport inside a helicon plasma source rely on electromagnetic simulations coupled to either kinetic or particle-in-cell strategies to reproduce the plasma response. If the plasma density reach values higher ... Mehr lesen

Analysis of High-Frequency Thermoacoustic Instabilities in Lean, Premixed Gas Turbine Combustors

F. Berger [1], T. Hummel [1], P. Romero [1], M. Schulze [1], B. Schuermans [2], T. Sattelmayer [1],
[1] Lehrstuhl für Thermodynamik, TU München, Germany
[2] GE Power, Switzerland

Modern gas turbine systems for power generation are prone develop so-called thermosacoustic instabilities in the combustion chamber. Physically, these instabilities emerge as large amplitude pressure oscillations within the combustor, which are caused by constructive feedback ... Mehr lesen

Electrical and Bubbly Flow Modeling of a Molten Salt Electrolysis Cell

A. Oury [1], P. Namy [1], A. M. Martinez [2] , K. S. Olsen [2], A. Solheim [2] ,
[1] SIMTEC, Grenoble, France
[2] SINTEF Materials and Chemistry, Trondheim, Norway

A laboratory-scale electrolysis cell for the recovery of metals is simulated with COMSOL Multiphysics® software. Two models are implemented: an electrical model simulating the current density (reaction rate) distribution at the electrodes and a laminar bubbly flow model which solves for ... Mehr lesen

Investigation of Thermal and Mechanical Factors on Distance Sensors in a Tow Bar

C. Mallwitz [1], L. Fromme [1], B. Sielhorst [2],
[1] University of Applied Sciences Bielefeld, Department of Engineering Sciences and Mathematics, Bielefeld, Germany
[2] Westfalia-Automotive GmbH, Rheda-Wiedenbrück, Germany

Most technical systems become smart over time, therefore those systems will have improved safety and comfort functions. An example is a new development by Westfalia-Automotive. A new generation of smart tow bars, equipped with a sensor system, including distance sensors, is able to ... Mehr lesen

Simulation of a Rotary Magnetorheological Damper

D. Harder [1], L. Fromme [1], R. Naumann [2],
[1] University of Applied Sciences Bielefeld, Department of Engineering Sciences and Mathematics, Bielefeld, Germany
[2] University of Applied Sciences Bielefeld, ISyM – Institute of System Dynamics and Mechatronics, Bielefeld, Germany

This paper presents a simulation model of a rotary damper filled with a magnetorheological fluid (MRF). The most important characteristic of the MRF is the variable viscosity, which can be controlled by an external magnetic field. In the simulation model, the fluid is described as a ... Mehr lesen

Simulation of Thermal Elastohydrodynamic Lubricated (TEHL) Gear Contacts

T. Lohner [1], A. Ziegltrum [1], K. Stahl [1],
[1] Gear Research Centre (FZG), Technical University of Munich (TUM), Garching, Germany

Thermal elastohydrodynamic lubricated (TEHL) contacts occur very frequently in drive technology and thus in gear drives. In this presentation, the implementation of a finite element based TEHL simulation approach for gear contacts in COMSOL Multiphysics® software is shown. The physically ... Mehr lesen

Visualisation of the Internal Processes of a Fuel Cell with the Help of an Application Built with the COMSOL Multiphysics® Software

A. George [1], L. Fromme [1]
[1] University of Applied Sciences Bielefeld, Department of Engineering Sciences and Mathematics, Bielefeld, Germany

The objective was to make a visualisation application for the pupil's lab of the University of Applied Sciences Bielefeld. The application serves as a supplement for a workshop. It should provide a better understanding of a fuel cell, to visualize important influences and collect first ... Mehr lesen

Transient CFD Investigation of a Photocatalytic Multi-tube Reactor

S. Denys [1], J. van Walsem [1], J. Roegiers [1], S. Lenaerts [1],
[1] University of Antwerp, Antwerp, Belgium

As in industrial countries, people spend most of their time indoors and the stringent heat-insulation measures in combination with deficient ventilation have a negative impact on indoor air quality, one approach for abating indoor air pollution is the integration or retrofitting of a ...
