In order to improve the design of an induction furnace and to optimize the charge melting, a COMSOL Multiphysics® application is developed. This application runs a furnace model. The inductor, supplied with an alternative electrical tension, creates a variable induction field B ⃗. Due to ... En savoir plus

The increasing demand for more efficient cooling options in the fields of fuel cell mobility and power electronics motivates for the development of novel cooling strategies with improved heat transfer. Forced convection of liquids is a common cooling method and allows high temperature ... En savoir plus

The nature of dark matter remains one of the most pressing puzzles in physics. The MAgnetized Disc and Mirror Axion eXperiment (MADMAX) is a dielectric haloscope dedicated to the search for QCD axion dark matter in the mass range of 40 - 400 µeV. The design of the experiment consists of ... En savoir plus

For automotive applications, HARMAN is using simulation and equalization methods to optimize audio systems. The fidelity of an audio system depends on many characteristics like the number of loudspeakers, the speaker packaging as well as the position and orientation of the speakers in ... En savoir plus

Concentration polarization (CP) is a common problem in membrane filtration. It is caused by the convective transport of large molecules towards the membrane surface, however while the solvent passes the membrane as permeate, the molecules are retained and accumulate at the membrane ...

We present a framework for patient-specific study of cardiac motion; in particular, we focus on the deformations of a beating Left Ventricle (LV), confronting numerical simulations with real data acquired by echo-cardiography. Our goal is to determine the clinical importance of the LV ... En savoir plus

Convective instability in a thin liquid layer is observed in many technical systems [1] and is of interest to the self-organization theory. To date, however, only simple problems with the convection between flat plates are well studied [2]. In real systems and devices, convective flows ... En savoir plus

Air core reactors are commonly used as shunt reactors, fault current limiting reactors, tuning reactors in capacitor banks. The absence of the iron-core results in a simple and lightweight construction. Consequently, the magnetic field of an air-core reactor is not guided within a ... En savoir plus

This work presents a small swimmer model in a low Reynolds number ($Re$) environment governed by the equation of motion for Stokes flow in COMSOL Multiphysics®. The entity, a few centimetres helical robot, is located inside of a pipe full of silicone oil, where the forces caused by the ... En savoir plus

A top-down nanosize mechanical resonator has been fabricated with a shape of a fractal. The self-similar structure consists of star-polygons and it is suspended over a 10 μm trench and has width of 12 μm. Its thickness of 0.040 μm is defined by the fabrication process and prescribes ...
