This paper shows how a time-dependent and non-linear simulation of the dynamic operation behavior of an induction machine is executed by means of the \"Rotating Machinery\" interface from COMSOL Multiphysics 4.2a. The two-dimensional FEM model is connected to electrical circuits by ... En savoir plus

In the modern food industry one of the most important problems to face is to preserve products from deterioration: a widely used solution is the convective foods drying. Drying is based on a simultaneous transfer of both heat and water that takes place when dry and warm air flows around ... En savoir plus

This study deals with a numerical investigation of the melting process of a PCM in a rectangular enclosure differentially heated. COMSOL Multiphysics is used in order to numerically solve Navier-Stokes and energy equations in the considered system. Adopting an enthalpy formulation, one ... En savoir plus

The use of plasmas for the treatment industrial effluents provides a new alternative to the decontamination of wastewater. The strong oxidizing species (O,O3, OH) generated by the plasma, at room temperature, can oxidise organic pollutants present in the water. Our simulation deals with ... En savoir plus

Fuel cells (FCs) are promising as an energy producing device, which at this stage of development will require extensive analysis and benefit from numerical modeling at different time- and length scales. COMSOL Multiphysics® is used to describe an intermediate temperature solid oxide fuel ... En savoir plus

Ventilation and Indoor Air Quality (IAQ) are issues of very high interest, determining comfortable conditions for occupants and no-contaminated local atmosphere. The aircraft cabins are more confined and have a higher occupant density than other indoor environments such as offices or ... En savoir plus

In this paper, a model for numerically obtaining lamb wave modes and dispersion curves in plates is presented. It is shown that COMSOL Multiphysics can be employed to simulate the behavior of guided waves in dispersive plates, which is useful for NDE applications. A two dimensional ... En savoir plus

In the medium term, gas hydrate reservoirs in the subsea sediment are intended as deposits for carbon dioxide (CO2) from fossil fuel consumption. This idea is supported by the fact, that CO2 hydrates are more stable than methane hydrates at certain conditions. The potential of producing ... En savoir plus

Energy performances and building energy quality can be achieved by high performance envelopes. In this paper the thermal performance of a naturally ventilated façade, applied to a traditional wall, widely used in existing buildings, was investigated by a transient simulation. A ... En savoir plus

We present a full modal -analysis of optical and acoustic properties based on two-dimensional finite-element method (2D-FEM) for Brillouin Gain spectrum (BGS) determination in optical fibers with COMSOL. This model enables us to predict precisely the BGS of any kind of silica fiber ... En savoir plus
