Finite element modelling of electrical machines usually assumes uniform magnetic properties and loss behaviour throughout the steel laminations. It is well known that manufacturing processes, like the assembly of the machine, deteriorate the properties of the core material. Generally, ... En savoir plus
A 2D transient heat conduction model was created in COMSOL Multiphysics to simulate temperature changes in material irradiated by a KrF laser beam confined on silicon’s surface. In this paper, the obtained results are shown and discussed in case of bulk Silicon. The heat source is ... En savoir plus
Surface acoustic wave (SAW) devices based on Rayleigh wave, shear wave, love wave, acoustic plate mode (APM) wave and flexural plate wave have been explored for sensors, actuators and telecommunication applications. An interdigital transducer (IDT) is a metallic comb-like structure ... En savoir plus
Corrosion and contact ohmic resistance of the stainless steel current collectors in molten carbonates is one of the greatest obstacles to widespread application of molten carbonate fuel cells (MCFC). We simulate the variation of material parameters values, accounting for the impact of ... En savoir plus
Vortex-induced vibration is a major cause of fatigue failure in submarine oil and gas pipelines and steel catenary risers. Even moderate currents can induce vortex shedding. In this paper, COMSOL Multiphysics is applied to study the flow pattern around submarine pipeline spans, and ... En savoir plus
A numerical analysis on transient three-dimensional temperature distribution in a semi-infinite solid, irradiated by a moving Gaussian laser beam, is carried out numerically by means of the code COMSOL Multiphysics. The investigated workpiece is simply a solid. A laser source is ... En savoir plus
A two dimensional instationary analysis of the conjugate optical-thermal fields induced in a multilayer thin film structure on a glass substrate by a moving Gaussian laser source is carried out numerically in order to compare back and front laser treatment processes. COMSOL Multiphysics ... En savoir plus
Impedance spectroscopy is a measurement technique that has been investigated in a wide variety of medical applications. An example is the measurement of the dielectric properties of the skin and underlying tissue using sensors placed in contact with human skin with capacitive fringing ... En savoir plus
CO2 capture and storage constitutes a promising solution to control and reduce these emissions. Wellbore integrity is a key challenge to ensure long term safety and for public acceptance. For this objective, a two-phase flow model in porous media based on Darcy’s law has been proposed to ... En savoir plus
Spark Plasma Sintering (SPS) is a promising rapid consolidation technique that allows a better understanding and manipulation of sintering kinetics and therefore makes it possible to obtain polycrystalline materials (ceramic or metallic) with tailored microstructures. A numerical ... En savoir plus
