Prototyping of a Claw Pole Machine Using 3D Modeling
This article is the result of a hobby project. The article is going thru the iterative developing process of a claw pole machine. In this developing process, simulating the magnetic flux density and back EMF waveform have been used to validate geometrical changes to the machine. En savoir plus
Heat Transfer in Adsorption Heat Exchangers between Pellets and Fins
Adsorption heat exchangers (AdHXs) are important components in adsorption heat pumps and chillers, a primary energy efficient source of heating and cooling. Due to availability and established inexpensive manufacturing fin-and-tube type heat exchangers with beds of adsorption pellets in ... En savoir plus
Electromagnetic Actuators Modeling, Simulation and Optimization: Review of Methods and Their Application for Switching Devices
Electromagnetic actuators are representing one important component of ABB's medium voltage reclosers [1, 2]. Their performance is strongly influenced by the considered material properties as well as by the electronic control units that will power the actuator. Depending on the studied ... En savoir plus
Computational Simulation of Gold Core/Shell Nanostructures for Near-Field Transducers in Heat-Assisted Magnetic Recording
A recurring problem, in heat assisted magnetic recording is the build-up of thermal energy in the near-field transducer leading to NFT deformation and the cessation of operation. A mechanism to dissipate this excess heat in the NFT without greatly effecting its’ plasmonic response is ... En savoir plus
Computational Modelling of Fluid Dynamics in Electropolishing of Radiofrequency Accelerating Cavities
Electropolishing is an electrochemical process that radiofrequency accelerating cavities undergo in order to improve their inner metal surface finishing. This is performed prior to their installation into particle accelerators, in order to enhance their accelerating properties. Using ... En savoir plus
Assessment of the SNR, G-Factor and Relative B1- Fields of Medical Radiofrequency Arrays
MRI relies upon a static magnetic field which creates a net magnetic moment from proton spins and radio-frequency fields are generated to excite this magnetic moment into a perpendicular plane, where it can be detected through the use of an array of conductive loops. The optimal size ... En savoir plus
Analysis of an Air Transparent Soundproof Window System & Comparisons to Physical Test Data
The design of windows and or other perforated structures which allow the free flow of air into & out of a building or system, while being fully soundproofed or attenuate certain frequencies is of great interest to architects and design engineers, where sound as a longitudinal wave, ...
