3D Dynamic Linear Electromagnetic Actuator Modeling and Simulation
Single coil actuators are representing one important component of ABB’s medium voltage reclosers. Their performance is strongly influenced by the considered material properties as well as by the electronic control units’ properties that will power the actuator. Therefore, this paper ...

Development and Optimization of a Microfluidic Device for Magnetic Field Induced Cell Separation
Besides conventional laboratory analysis methods, so called micro-total-analysis devices (µTAS) have gained great interest during the last decades. In this work we demonstrate a mechanism for the separation and selection of medical samples that can be applied within these µTAS devices. ... Per saperne di più

Multiphysics Process Simulation of the Electromagnetic-Supported High Power Laser Beam Welding of Austenitic Stainless Steel
The application of an oscillating magnetic field on the high-power full-penetration laser beam welding process of a 20 mm thick stainless steel plate was numerically and experimentally investigated. In the simulations, three-dimensional heat transfer and fluid dynamics as well as ... Per saperne di più
Sub-Millimetric Vacuum Electron Gun Design and Characterization
This paper presents the design of an electron gun that could be employed for vacuum tubes operating in the THz range. In this context, vacuum tubes one of the main difficulties in the realization of THz vacuum tube is the design and the realization of the electron gun. Since the ... Per saperne di più
Universal Dielectric Response of Atmospheric Ice Using COMSOL Multiphysics®
Heterogeneous materials with different phases, are conductive and insulating (dielectric), and are physically present in different natural materials as e.g. atmospheric ice. Jonscher’s proposed ‘universal dielectric response’ is not sufficient for such materials, as it only reflects ... Per saperne di più
The Fast Model for Ionic Wind Simulation
Ionic wind is the gas flow induced by the corona discharge. Ions produced by corona are accelerated by electric field and transfer their momentum to neutral molecules. Using ionic wind one can convert electric energy to kinetic energy of air flow almost directly. The phenomenon of ionic ... Per saperne di più
Simulation of a Single-Sided Magnetic Particle Imaging Device with COMSOL Multiphysics®
For the MPI imaging process, superparamagnetic iron oxide nanoparticles (SPIONs) are used as tracer material. The particles are excited by a sinusoidally varying magnetic field. A field-free point (FFP) is generated by the superposition of two magnetic fields. The FFP is important for ... Per saperne di più
Optimizing Transducer Configuration of Capacitive Sensors for Agricultural Applications
This work aims to determine optimized configuration using COMSOL Multiphysics® for a class of transducers. Two types of capacitive sensors needed for monitoring and control in agriculture are investigated: a rain sensor and a soil humidity sensor. COMSOL Multiphysics® is used to test ... Per saperne di più
