The electromagnetic pumping (EMP) of electrically-conducting fluid is of growing interest for many industrial applications requiring precise flow control, enabling stopping or reversing flow direction without any moving parts or mechanical devices. Presented in this work are the results ... En savoir plus
In this study, a biomimetic vibrating 3D MEMS Gyroscope is designed, consisting of two circular diaphragms with a club shaped structure placed over one of them. This MEMS based vibrating gyroscope was modeled and simulated using COMSOL Multiphysics 4.1 - MEMS module. The purpose of the ... En savoir plus
A very simplified system for high voltage test is studied, considering reason for voltage holding failures which are not covered by conventional and local design criteria. A first understanding of the problem is obtained by solving the electrostatic potential in a 2D axis symmetric ... En savoir plus
A common pyrometallurgical route for the recovery of numerous metals and rare earths is high-temperature molten salt electrolysis. This process involves an electrolyte made of a molten salt in which the metal to be recovered, most commonly present in its oxide form, is dissolved. When a ... En savoir plus
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 ... En savoir plus
Accurate and efficient computation of electrical parameters for different conducting bodies represents an essential part of spacecraft modern integrated circuits. In this paper, we will illustrate modeling of inhomogeneous quasi-TEM shielded rectangular, cylindrical, and triangular ... En savoir plus
The steady-state non-equilibrium distributions of two species of mono-valent ions around a charged nanofluidic channel have been examined. Large reservoirs were placed on either side of the nanoscale channel to simulate bulk concentration of ions in a fluid. Results from COMSOL ... En savoir plus
Permanent Magnet Flowmeter (PMFM) is a non invasive device, which is used to measure the flow of electricallyconducting sodium in Fast Breeder Reactor Circuits. PMFM works on the principle of generation of motional EMF by magnetic forces exerted on the charges in a moving conductor. In ... En savoir plus
In this paper, SF6 gas insulated voltage instrument transformer (VIT) is designed and implemented and also tested electrostatically. A complex model consisting of air bubbles inside the epoxy cast resin is used for computer tests. The standard lightning over voltages is applied according ... En savoir plus
This paper presents the quasi-TEM two-dimensional (2D) approach for the analysis of multiconductor transmission lines interconnect in single and two-layered dielectric region using the finite element method (FEM). FEM is especially suitable and effective for the computation of ... En savoir plus
