Finite Element Modeling and Simulation of Electromagnetic Forces in Electromagnetic Forming Processes: Case studies using COMSOL Multiphysics

A. N. Kumar[1], and M. Nabi[1]
[1] Department of Electrical Engineering, Indian Institute of Technology Delhi, India

Electromagnetic Forming (EMF) is a promising and relatively new manufacturing technology having significant advantages over conventional forming processes. A primary characteristic of this process is use of noncontact electromagnetic forces to achieve forming and shaping of various ... En savoir plus

Kinetics of the Carbothermal Reduction of Ilmenite: Grain Pellet Model

S. Savithri[1], and M. S. Manju[1]
[1] National Institute for Interdisciplinary Science and Technology Trivandrum, India.

A novel mechanism for the carbothermal reduction of Ilmenite is proposed and validated with the help of a comprehensive mathematical model. A time-dependent isothermal pellet-grain model is used to simulate the kinetic behaviour of a spherical pellet of ilmenite (FeTiO3) in CO/CO2 ... En savoir plus

Magneto-structural Analysis of Fusion grade Superconducting Toroidal Field Coils

A. Amardas [1], and S. Dwivedi[2]
[1] Institute for Plasma Research, Gandhinagar, Gujarat, India
[2] COMSOL Multiphysics Pvt. Ltd, Bangalore, Karnataka , India

In this paper, detail magnetostructural analysis of fusion grade superconducting toroidal field coils that are used in ‘tokamaks’ is presented. The stresses that arise due to Lorentz forces in large size superconducting coils that carry high currents are of catastrophic type in nature. ... En savoir plus

Thermal analysis of a spent fuel transportation cask

P. Goyal[1], V. Verma[1], R. K. Singh[1], and A. K. Ghosh[1]
[1]Reactor Safety Division, Bhabha Atomic Research Centre, Trombay, Mumbai, India

Spent fuel transportation casks are required to meet among others (test conditions), the regulatory thermal test conditions in order to demonstrate their ability to withstand specified accidental fire conditions during transport. This paper describes the transient thermal analysis ... En savoir plus

Analyzing the Influence of Electric Field on Flame Through Electro-Hydrodynamics

S. Mitra[1], P. Sharma[2], M. Godbole[2], and M. Kumar KM[2]
[1] Department of Mechanical Engineering, Indian Institute of Technology Madras, Chennai, Tamil Nadu, India

[2] GE Global Research, Bangalore, Karnataka, India

The effects of electric fields on combustion flames have been studied by using several types of experimental techniques as well as few numerical methods. The flame is influenced by the electric field mainly due to the charges present as a result of chemical reactions that take place in ... En savoir plus

Mobility of Catalytic Self-Propelled Nanorods Modeling with COMSOL Multiphysics^®

F. Lugli[1] and F. Zerbetto[1]
[1]Department of Chemistry “G. Ciamician”, Università di Bologna, Bologna, Italy

A small particle or a nano-sized object placed in a liquid is subject to random collisions with solvent molecules. The resulting erratic movement of the object is known as Brownian motion, which, in nature, cannot be used to any practical advantage both in natural systems (such as ... En savoir plus

A Time Dependent Dielectric Breakdown (TDDB) Model for Field Accelerated Low-K Breakdown Due To Copper Ions

R. Achanta, J. Plawsky, and W. Gill
Department of Chemical and Biological Engineering, Rensselaer Polytechnic Institute, Troy, NY, USA

We have simulated the copper ion concentration and internal electric field profiles in a dielectric material by solving the transient continuity/Poisson equations using COMSOL Multiphysics. We have shown that failure of dielectrics can be modeled if we assume that failure in Cu/SiO2/Si ... En savoir plus

Stochastic Approach in Approximation of the Transient Plasma Sheath Behavior in FEM

J. Brcka
TEL US Holdings, Inc., Albany, NY, USA

Recently, the advanced plasma tools have been using very high frequency power sources (>100 MHz) and their combination to excite plasma utilized in semiconductor technology. This approach is evoking the regimes that are less understood and currently a subject to many studies and ... En savoir plus

Finite Element Analysis of Ferrofluid Cooling of Heat Generating Devices

T. Strek
Institute of Applied Mechanics, Poznan University of Technology, Poznan, Poland

An external magnetic field imposed on a ferrofluid with a temperature gradient, results in a non-uniform magnetic body force, which leads to a form of heat transfer called thermomagnetic convection. A magnet placed near the device will always attract the colder ferrofluid more than ... En savoir plus
