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 ... En savoir plus

INVELOX is an innovative wind power generation system as shown in Figure 1. It is comprised of a wind capturing system that accelerates and delivers high kinetic energy wind to a power conversion system placed in the Venturi section of the INVELOX. The objective of this project is to ... En savoir plus

Heat and mass transfer through a gypsum board exposed to fire is simulated and compared to experimental data. The gypsum board is modeled as a porous medium with moist air in the pores. A dehydration front develops at the fire side and travels through the board, consuming energy and ... En savoir plus

In this paper we want to figure out the development of a capacitive acceleration-sensor system with the FEM-Method. The sensor-system is in the position to detect accelerations in the range of ±20 g. Furthermore the sensor-element contains a printed RF-inductance, which is used for ... En savoir plus

Thomas Frommelt received his PhD in physics in 2007 from the University of Augsburg for experimental work and simulation analysis on acoustically driven microfluidic mixing. In 2008, he joined the SGL Group and introduced COMSOL Multiphysics as the tool for flexible equation based ... En savoir plus

This paper deals with a numerical investigation on sliding door and people moving effects on the indoor climate of a standard ISO5 class OT with an ultraclean air filter system and a total ceiling unidirectional diffuser. A simple method to analyze the effects on the OT climate by ... En savoir plus

Simulation of components and processes becomes more and more important in industry; therefore it is necessary to train young engineers how to apply simulation software. We established two consecutive courses for graduate students in which we decided to focus on COMSOL Multiphysics®, ... En savoir plus

The roof of a well known shopping place in Amsterdam collapsed during a storm with heavy rain showers in 2002. One of the main problems was the malfunction of the draining system. Another problem was that driving rain water apparently washed over edges that where designed to hold the ... En savoir plus

Bionics is the scientific discipline between biology and technology. The aim of bionics is to recognize natural design principles and derive technical solutions. Natural structures have been optimized over generations by evolution. In most cases the minimization of the energy demand is a ... En savoir plus

Calculations were carried out for the water model of the investigated tundish, represented on a scale 1:3. Numerical calculations enable to estimate the fluid flow velocities, pahtlines and other parameters. Calculations were done for two different grids. Based on the results, the flow ... En savoir plus
