A Comparison of FDFD and FEM Methods Applied to the Buried Mine Problem

R. W. Gamache, C. Rappaport, and M. Farid.
TransTech Systems inc., Northeastern University

The major impediment to detection and characterization of low dielectric contrast nonmetallic buried in soil is the distorting and masking effects of clutter from rough ground surfaces and soil volumetric inhomogeneities. In this work, a 2D FDFD code developed specifically for the buried mine...

Solidification of a Liquid Metal Droplet Impinging on a Cold Surface

Tanai L. Marin,
Faculty of Physics and Mathematics Sciences,
Department of Mining Engineering,
University of Chile,
Santiago, Chile

A method for the solidification of a free surface liquid phase is presented and solved with COMSOL Multiphysiscs using a fixed grid.

In this case, the Level set method with phase re-injection for mass conservation is used to prescribe the movement of the free surface of the liquid...

Thermal and Velocity Field Analysis Inside an Historical Building - The Hall of the Two Hundred

C. Balocco
Energy Engineering Department, Firenze

For museums and the like, the indoor climatic conditions should preserve the exhibited works of art and ensure comfort conditions for people visiting or working inside them. The present paper concerns a primary study of the Hall of the Two Hundred of the Old Palace in Florence. General 3D...

Modeling Remote H2 Plasma in a Semiconductor Processing Tool

J. Brcka
TEL Technology Center, America, LLC

Hydrogen plasma is typically used in the semiconductor industry for materials processing, surface preparation and cleaning of silicon wafers and thin films. In this contribution, we developed a 2D/3D plasma fluid model as described by the set of the species and energy balance equations in a...

Coupled Electromagnetic, Thermal and Fluid Dynamics Simulation of Axial Flux PM Synchronous Machines

F. Marignetti
DAEIMI, Department of Automation, University of Cassino, Cassino, Italy

This paper investigates the Electromagnetic and thermal behavior of Synchronous Axial Flux Permanent Magnet Machines.

The Axial Flux machine employed for tests and simulations has a Soft Magnetic Compound stator core. The electromagnetic analysis is used to assess electromechanical...

Finite-element Modeling of Elastic Surface Modes and Scattering from Spherical Objects

O. Falou1, J. C. Kumaradas2, and M. C. Kolios1,2
1Dept. of Electrical and Computer Engineering, Ryerson University, Toronto, ON, Canada
2Dept. of Physics, Ryerson University, Toronto, ON, Canada

In this work, backscatter from an elastic sphere was used to validate the computational model against analytical solutions (Faran theory).

Agreements between analytical and finite element solutions were found in the scattered far-field over a range of frequencies of interest (10 - 70...

Vibration Analysis - Gullfaks C Knock Out Drum

S. Sandström

An eigenvalue as well as a harmonic response analysis is performed on the Gullfaks C, Knock Out Drum (KOD) including some of the connecting pipe systems. The vibration behavior of two new choke valves and their specific connection to the KOD are of special interest. The main concern is the low...

Ultrasound Propagation in Viscoelastic Material Guides

Castaings, M.1, Predoi, M.V.2, Hosten, B.1 1 Laboratoire Mécanique Physique, Univ. Bordeaux 1, UMR CNRS 5469, Talence, France
2 Catedra de Mecanica, Universitatea Politehnica Bucuresti, Bucuresti, Romania

Wave propagation in elastic waveguides is a problem of constant interest from the last decades. Several numerical approaches exist. The most intuitive uses time-marching routines that solve the equations of dynamic equilibrium and supply displacements of the structure nodes as time functions. This...

Beam Characteristics of Ultrasonic Transducers for Underwater Marine Use

G. McRobbie1, P. Marin-Franch2, and S. Cochrane1
1 University of Paisley
2 Piezo Composite Transducers, Ltd

This paper illustrates how finite element analysis with COMSOL Multiphysics can be used to simulate the mechanical and electrical characteristics of piezoelectric transducers. It also shows how beam transmit plots and performance measurements can be modeled by coupling between a piezo domain...

Predicting Tsunami Waves by Combining Analytical and Finite Element Methods

N. Aage, R. Sigurbjörnsson, S. Laustsen, and O. Skovgaard
Technical University of Denmark

In this paper, a simple tsunami wave problem is studied. The geometry of consideration is an infinite ocean with appreciable variations of the ocean bottom. Long-wave theory is applied and the flow equations are linearized over depth. It is verified that it is possible to combine the use of...
