Glass containing nanoparticles is a promising material for various photonic applications due to the unique optical properties mainly resulting from the strong surface plasmon resonance (SPR) of the silver nanoparticles. The characteristics of the resonance can be modified by varying size, shape and concentration of the particles. A finite element method (FEM) implemented in the software COMSOL ...

The Cosserat models fall into the group of the extended continuum media. They are capable of treating the size effects (characteristic length) in a natural manner using six material moduli for the isotropic elastic cases instead of two (and) for the classical continuum mechanics. This model involves two constitutive laws corresponding to two kinds of balance equation. The first one handles the ...

In this study, COMSOL Multiphysics is applied in order to simulate reacting flows for duct burner systems arranged in the post-firing section of a Heat Recovery Steam Generator of a combined cycle power plant. Two- and three-dimensional simulations are carried out in order to investigate on operative conditions mainly responsible of duct burners overheating. The results are obtained for several ...

This paper presents the mathematical modeling for the analysis of the magnetostrictive materials, which describes the behaviour of the magneto-mechanical coupling in a rod of magnetostrictive material and capturing it in COMSOL® to produce a predictive and detailed analysis. A simulation of the behaviour under harmonic excitation is done in this work.

Temperature and residual moisture content of a stationary Textile in a home tumble dryer are simulated in a 2D model with COMSOL Multiphysics. Moisture migration to the textile surface is modeled in the form of capillary flow and vapor diffusion along with heat transfer in the form of conduction and energy lost due to phase change (evaporation). The drying air energy, mass and momentum transport ...

We describe the modeling of microdisk lasers displaying vertical emission. The devices are THz quantum cascade lasers with metallic gratings fabricated along the circumference. The emission properties of the fabricated devices are well explained by the model, good mode control is obtained, and the collected power from a patterned device is increased 50 times with respect to unpatterned ...

Phosphoric acid doped polybenzimidazole (PBI) membranes are commonly used in today’s high-temperature polymer-electrolyte-membrane (HTPEM) fuel cell technology. COMSOL Multiphysics is used to model and simulate the three-dimensional, single-phase, non-isothermal overall cell behaviour at different operating points. The sol-gel PBI/H3PO4 membrane behaviour is modeled using an Arrhenius ...

In this paper an electromagnetic solenoid actuator (EMVA) consisting of an upper and lower electromagnet, a linear moving armature and two preloaded springs is considered as a potential approach in Variable Valve Actuation (VVA) Systems for Internal Combustion Engines. In opposition to common approaches the underlying EMVA make use of a permanent magnet in the upper electromagnet. The analysis of ...

We present time-resolved methods that rely on near-infrared photons to image the optical properties and distribution of fluorescent probes in small laboratory animals. The coupled diffusion equations of excitation and fluorescence photons in highly scattering tissues were solved using the three-dimensional Finite Element Method (FEM) provided by COMSOL. The computed results allowed to yield ...
