Notez que de nombreux exemples présentés ici sont également accessibles via la Bibliothèques d'Applications intégrée au logiciel COMSOL Multiphysics® et disponible à partir du menu Fichier.
The primary defense of a submarine lies in its capacity to remain hidden during operation. As radio waves are strongly absorbed by sea water, sound navigation ranging, or SONAR, is one of the main methods used for the detection of submarines. SONAR systems are also used for underwater ...

This model file was used for creating the plots featured in the blog post "How to Model Ion-Exchange Membranes and Donnan Potentials". En savoir plus
Active magnetic bearings are often used for controlling the vibration level in mechanical systems. In this example, a motor driven rotor system in which the speed of the system is gradually increased is considered. The system vibrates due to existing imbalances. As the rotor speed ...

This tutorial demonstrates a full electro-vibroacoustic analysis of a conceptual electrostatic speaker driver, composed of thin conducting plastic diaphragm residing between two perforated metal sheets called grids or stators. When an audio signal is applied to the grids (out of phase), ... En savoir plus
This model treats the free convection of argon gas within a light bulb. It shows the coupling of heat transport (conduction, radiation and convection) to momentum transport (non-isothermal flow) induced by density variations caused by temperature. COMSOL Multiphysics model makes it ... En savoir plus
Loudspeaker design is a challenging task, where the design objective is to achieve better sound quality without violating manufacturing and operational constraints. The quality of sound depends on many parameters; one of them is the ability to control, damp, and shift the diaphragm ... En savoir plus
Micromirrors are used in certain MEMS devices to control optic elements. This model of a vibrating micromirror surrounded by air uses the Thermoacoustic-Shell Interaction user interface to model the fluid-solid interaction, and it thus includes the correct viscous and thermal damping of ...

Recovery of precious metals in recycling of electronics, or extraction from ore, is usually performed through leaching of the metal into an aqueous phase. Precious metals require the use of an oxidant, and often, a complexant. In the case of gold, the cyanide anion (CN-) forms a soluble ... En savoir plus
In general, there are two classes of ventilation: mixing ventilation and displacement ventilation. In displacement ventilation, air enters a room at the floor level and displaces warmer air to achieve the desired temperature. Heating sources in the room can include running electronic ...
