A compression driver is a certain type of electrodynamic loudspeaker which has a phase plug with slits in front of the diaphragm. The slits are narrow enough that the so-called viscothermal effects are of significant importance. In this paper a 2D axisymmetric finite element model of a ... Per saperne di più
This elaboration presents a pre-study on automatic rotor construction for the flywheel energy storage system dedicated to operate in the levitation mode. The optimization profile model is used as a basic profile source. The 3D flywheel shape is generated on the base of obtained ... Per saperne di più
State of the art proximity sensors are most often based on optical or tactile methods. Although these sensor systems are widely used (e.g. clamping protection) the reveal several drawbacks. Most optical sensors need a line of side whereas tactile sensors cannot be used to determine a ... Per saperne di più
There is a considerable world-wide interest among lightning protection engineers and designers on the improvement of the standard procedures to assess the location of the most vulnerable places on complex structures to be struck by lightning flashes. This paper presents the ... Per saperne di più
Glow corona discharges are generated from tall objects during thunderstorms previous to a lightning strike. These discharges generate space charge which can hinder the development of subsequent discharges. In order to quantify the shielding effect of positive glow corona, a transient, ...

Since October 2009 the laboratory of ATE has carried out collaborative research with the WTD 71 that aims for prediction, reduction and optimization of so-called underwater electric potential (UEP) signatures. COMSOL is used to simulate potential distributions in the context of impressed ... Per saperne di più
Even though the researches in synchronous machines are advanced, the practical design still is a problem because of the complex interaction between several design parameters. The project “EaSync” at the Ostfalia University focuses on the bundling of machine models using COMSOL ... Per saperne di più
3D FEM simulation of millimeter-scale, complex electro-optically induced waveguide based devices demands the use of grids with more than several million nodes. Hence the simulation could take substantial time and require large amounts of available memory. This paper presents a ... Per saperne di più
Lorentz Force Velocimetry (LFV) is a non-contact measurement technique used to determine flow rates in electrically conducting fluids by exposing the flow to an external magnetic field and measuring the Lorentz force acting on the magnet system. Typically, for LFV applications real and ... Per saperne di più
A simple magnetic circuit consisting of ferromagnetic core material, air gap, permanent magnets and current coils can be used to form magnetic actuators, motors etc. devices. In this work the current coils are not used to generate working magnetic field, but just to switch magnetic flux ... Per saperne di più
