A compression driver is a certain type of electrodynamic loudspeaker which has a phase plug with slits in front of the diaphragm. The slits are narrow enough that the so-called viscothermal effects are of significant importance. In this paper a 2D axisymmetric finite element model of a ... En savoir plus
The efficiency of bioreactor lanfills depends on a homogeneous distribution of leachate in the waste body. Therefore, optimisation of leachate injection systems is a challenging issue for operators. Most studies have shown that surface Electrical Resistivity Tomography (ERT) can be a ... En savoir plus
The purpose of this work is to investigate the triggering behaviour of safety fuses for mobile on board supply systems. The influence of different materials and shapes of the fuses on the triggering behaviour are analyzed. Furthermore, the simulation results obtained by the use of COMSOL ... En savoir plus
Dielectrophoresis is a method for cell manipulation in miniaturized devices exploiting the dielectric properties of cells and/or cellular aggregates suspended in a fluid and subjected to a high-gradient electric field. The mathematical expression of the force is obtained by a multipole ... En savoir plus
The purpose of this paper is to present a numerical modeling of plasma phenomena in beryllium emissions using COMSOL Multiphysics software. The Beryllium films were deposited on mirror polished fine grain graphite substrates using the Thermionic Vacuum Arc (TVA) technology available at ... En savoir plus
The performance of biofilters relies on the presence of a sufficient amount of water in the biofilter material. And breakdown of filtration performance is often caused by inappropriate water content. The present study focuses on the drying dynamics within such filter, which are modelled ... En savoir plus
We treat a gradient constrained minimization problem which has applications in mechanics and superconductivity. A particular case of this problem is the elastoplastic torsion problem. In order to solve the problem we developed an algorithm in an infinite dimensional space framework ... En savoir plus
The main aim of the present work is the study of the thermal and energy performances of the new hall of the Old St.Maria Nuova Hospital in the center of Florence (Italy). Transient simulations were carried out of the 3D model of the hall to analyse the air flow patterns, distribution and ... En savoir plus
Here we present and discuss numerical solutions to the paraxial wave equation using COMSOL (2D, PDE, General Form, time-dependent analysis). Ultimately, the goal is to extend this treatment of free-space beam propagation to the case of propagation through a medium that is non-uniform ... En savoir plus
Traditionally the design cycle for magnetic fields involves guessing at a reasonable conductor and magnetic material configuration, using finite element analysis (FEA) software to calculate the resulting field, modifying the configuration, and iterating to produce the desired results. We ... En savoir plus
