A numerical investigation of the long-term performance of double U-tube borehole heat exchanger (BHE) fields, in the case of non-negligible effects of groundwater movement, is performed by means of COMSOL Multiphysics. Two time periodic heat loads, with a period of one year, are studied: ... En savoir plus
Distributed Feedback Fiber Laser (DFB-FL) sensors are increasingly used in aeronautical applications. One of the newest such applications consists in detecting the “transition” zone between laminar and turbulent air flow upon the extrados surface of an aircraft wing. In this specific ...

This study investigates the feedback between fault slip and dike intrusions during the Mono-Inyo eruption sequence of ~1350 A.D. (Mono Basin, California). We perform an extensive validation of 3D finite element models, implemented in the Structural Mechanics module of COMSOL ... En savoir plus
In COMSOL Multiphysics it is possible to implement and simulate several independent models in parallel. This can be meaningful when the different models are coupled to each other by some kind of interaction. If a part of the geometries is identical in all models, this part can be reduced ...

The finite-element method (FEM) (COMSOL RF Module) has been employed for modal analyses of porous silicon (PSi) waveguides composed of a guiding layer of low porosity (high refractive index) on a cladding layer with higher porosity (lower refractive index). These can be made by switching ... En savoir plus
Porous membranes with pore sizes in the micrometer scale are required in many micro systems dedicated to biological and chemical applications. If their thickness is in the same dimension like the pore diameter they are called microsieves. On the one hand, a thin membrane guarantees a ... En savoir plus
The fabrication of piezo aluminium composite modules for sensor and actor applications with mass production technologies is in the scope of the SFB/Transregio 39 PT-PIESA project funded by the (German Research Foundation). After forming of cavities with a width of 0.3 mm into aluminium ... En savoir plus
Electrochemical Machining is a potential procedure for micro manufacturing technology. Especially the absence of machining forces makes it advantageous for processing metals with high hardness and for the generation of complicated geometries. Applying a closed electrolytic free jet (Jet ... En savoir plus
Simulation tools for building physics problems play an important role in design and understanding the behavior of energy efficient buildings. There are different tools available for simulation of these problems, but each simulation tool has its own advantages and limitations. In this ... En savoir plus
The axial injection torch (AIT) produces high-density plasmas by coupling microwave power to a flowing gas. The plasma is imposed by defining its electron density and temperature whose maximum are given by optical emission spectroscopy diagnostics. Our study of an AIT with COMSOL ... En savoir plus
