Reactive Transport Processes in Compacted Bentonite

A.E. Idiart[1], M. Pekala[1], A. Nardi[1], D. Arcos[1]
[1]Amphos 21, Barcelona, Spain

The Swedish Organization for Radioactive Waste (SKB) is considering disposal High Level Wastes in a deep underground repository. Bentonite clay is planned to be used in the near-field of the waste packages as buffer material. The buffer is expected to provide a favorable environment with ... En savoir plus

Single Crystal Diamond NEMS Switch

M. Liao
Optical and Electronic Materials Unit
National Institute for Materials Science
Japan

A single-crystal diamond NEMS switch was fabricated while batch production of SCD MEMS/NEMS structures were developed. The diamond NEMS switches exhibit high performance with respect to high controllability, high reproducibility, and good reliability. Modeling and simulations were made ... En savoir plus

Estimation of Fluid Pressure in the Process of Magneto-rheological Flow Finishing

S. Chothe[1], P. Ranjan[1], Dr. P.M. Pawar[1], A.B. Shinde[1]
[1]SVERI's College of Engineering, Pandharpur, Maharashtra, India

This paper presents the 3D model of pressure distribution in the process of magneto-rheological flow finishing. The effect of working gap on pressure distribution is studied using COMSOL Multiphysics® software. Also, the effect of different viscosity of fluids on development of pressure ... En savoir plus

Matching 4D Porous Media Fluid Flow GeoPET Data With COMSOL Multiphysics Simulation Results

Spacecrafts have a prime necessity that their temperature be controlled. This paper presents the simulation of a mechanically actuated field effect transistor that is used in a thermal system. It comprises of a composite beam, a piezoelectric substrate and a field effect transistor. The ... En savoir plus

A Finite Element Test of the 2002-2003 Etna Eruption

F. Pulvirenti[1][2], M. Aloisi[1], G. De Guidi[2], M. Mattia[1], and C. Monaco[2]
[1]Istituto Nazionale di Geofisica e Vulcanologia, Sezione di Catania, Catania, Italy
[2]Dipartimento di Scienze Geologiche, Università di Catania, Catania, Italy

Structural, morphological and ground deformation studies suggest that the eastern flank of Mt. Etna (eastern Sicily) is spreading seaward. Three contrasting models have been proposed: deep-seated spreading, shallow sliding and tectonic block movements. In order to better understand the ... En savoir plus

Simulation of Thermal Sensor for Thermal Control of Satellite Using COMSOL Multiphysics

G. Mangalgiri
BITS Pilani K K BIRLA GOA CAMPUS
Zuarinagar
Goa, India

The actuator comprises of a temperature sensitive composite deflecting beam, a piezoelectric substrate and a field effect transistor. The temperature rise causes an expansion in the composite beam thereby causing it to deflect. The deflecting beam impinges on the piezoelectric crystal ... En savoir plus

Microwave Heating at the Grain Level

S. Lefeuvre[1], and O. Gomonova[2]
[1]Eurl Creawave, Toulouse, France
[2]Siberian State Aerospace University, Krasnoyarsk, Russia

The microwave heating and processing of heterogeneous material is usually simulated using a set of coupled PDE equations in an homogeneous medium. Nowadays it is possible to describe more accurately the process with a suitable description of the heterogeneities that is at the grain ... En savoir plus

Numerical Simulation of the Functional Electromagnetic Stimulation of the Human Femoral Bone using COMSOL

Y. Haba[1], W. Kröger[2], H. Ewald[2], R. Souffrant[1], W. Mittelmeier[1], and R. Bader[1]

[1]Biomechanics and Implant Technology Research Laboratory, Department of Orthopaedics, University of Rostock, Rostock, Germany
[2]Institute of General Electrical Engineering, University of Rostock, Rostock, Germany

In the present study we determined the relative conductivities and permittivities of fresh cortical and cancellous bone measuring human femoral heads in different slices of 1 mm thickness. The identified conductivities of human trabecular bone are used for the electromagnetic field ... En savoir plus

Punch Design for Uniaxial Forging Process of γ-TiAl Using COMSOL Multiphysics^®

R. Cagliero[1] and G. Maizza[1]
