Introduction to COMSOL based Modeling of Levitated Flywheel Rotor

A. Pilat
AGH University of Science and Technology
Kraków, Poland

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 ... Read More

Modeling of Rotating Magnetic Field Eddy Current Probe for Inspection of Tubular Metallic Components

T. V. Shyam[1], B. S. V. G. Sharma[1], K. Madhusoodanan[1]
[1]Bhabha Atomic Research Centre, Mumbai, Maharashtra, India

Rotating Magnetic Field Eddy current technique is a promising technique for inspection of flaws in metallic tubular components. Three primary coils, 120 degrees apart in space, are excited with three phase current source, by virtue, a rotating magnetic field polarised ... Read More

Green's Function Approach to Efficient 3D Electrostatics of Multi-Scale Problems

C. Roman [1], L. Schmid [1], L. Stolpmann [1], C. Hierold [1],
[1] ETH, Zurich, Switzerland

We present an efficient method to compute efficiently the general solution (Green's Function) of the Poisson Equation in 3D. The method proves its effectiveness when dealing with multi-scale problems in which lower dimensional objects, such as nanotubes or nanowires (1D), are embedded in ... Read More

Multiphysics Analysis of Electromagnetic Flow Valve

J. S. Crompton [1], K. Koppenhoefer [1], S. Yushanov [1],
[1] AltaSim Technologies, Columbus, OH, USA

Solenoid valves control fluid flow by using the passage of an electric current to produce a magnetic field that controls the displacement of a pre-tensioned plunger. As the electric current increases, the induced force causes the plunger to move upward against the force exerted by a ... Read More

Finite Element Modeling of Transient Eddy Currents in Multilayer Aluminum Structures

V. Babbar[1], and T. Krause[1]

[1]Department of Physics, Royal Military College of Canada, Kingston, Ontario, Canada

Transient eddy current (TEC) technique is being developed for detection of flaws located at depth within multilayer aluminum structures. The present work involves finite element modeling using COMSOL Multiphysics software to simulate different types of probes by changing some of these ... Read More

Determination of Electric Potential Distribution and Cell Resistance of a Uranium Electrorefining Cell

Indira Gandhi Centre for Atomic Research, Kalpakkam 603 102, Tamil Nadu, India

Electrorefining is an electrolytic process for obtaining high purity metal. In this process the impure metal is made anode and the high purity metal is deposited on cathode. Electrorefining is a key step in pyrochemical reprocessing of spent fuel from metal fuel fast reactors. ... Read More

Traveling Plasma Wave Levitation of Objects Supported by Coanda Effect new

R. Eisenschmid[1]
[1]OPTIMA pharma GmbH, Schwäbisch Hall, Germany

Electrostatically excited plasma waves can induce a “plasma wind” in the surrounding media or air. The lifted object has a shape of a flying saucer, just for better illustration. A travelling plasma wave propulsion requires a pre-ionized media around the surface and a travelling ... Read More
