Modelling the Thermal Impact of a Repository for High-Level Radioactive Waste in a Clay Host Formation

X. Sillen
Belgian Nuclear Research Centre (SCK-CEN), Waste & Disposal Department, Mol, Belgium

Disposal in deep clay geological formations is one of the promising options for disposal of high-level radioactive waste. Yet, they can generate considerable amounts of heat as a side effect of radioactive decay. This paper shows how COMSOL Multiphysics has been used to evaluate the physical impacts of the heating on the geological media around a deep disposal system. The software was found ...

National Institute of Technology Tiruchirapalli, Tamil Nadu, India

A proximity DC current sensor using of a piezo sensed and actuated cantilever beam with a permanent magnet mounted at its free end is designed and simulated in COMSOL Multiphysics. The change in resonant frequency of cantilever is a measure of the current through the wire. The sensor is found to be linear with good sensitivity.

The Huygens Atmospheric Structure Instrument (HASI) was designed to characterize the physical properties of the lower atmosphere and surface of Titan, the planet-size moon of Saturn. The Relaxation Probe (RP) sensor on the Huygens probe, determined the electrical conductivity in the lower atmosphere of Titan, from 140 km to 40 km. It was suspected that at an altitude above 100km, the booms ...

Simulation Of A Hydrogen Permeation Test On A Multilayer Membrane

Laboratoire d’Etude des Matériaux en Milieu Agressif, LEMMA, Bat. Marie Curie, La Rochelle, France

To understand a metal susceptibility to Hydrogen Embrittlement (HE), it is important to quantify the diffusion of hydrogen through a metallic membrane. Electrochemical permeation tests are the most common methods for experimentally determining the diffusion coefficient of a metal. However the parameters directly accessible from experiments are the time required for a stream to be observed and the ...

Modelling Electric Fields in High Voltage Submersible Changeover Switch

K. Follesø
Bennex AS, Bergen, Norway

Controlling electric field distribution in high voltage components is critical to avoid excessive electric stress on the insulation and thus reducing the risk of insulation breakdown and damage to equipment. For subsea applications this is even more important due to the costs involved in accessing and replacing the damaged parts. This paper describes how COMSOL Multiphysics has been used for ...

Dynamic Model for Catenary Mooring: Experimental Validation of the Wave Induced Load

[1]DICAM, Università di Bologna, Italy
[2]Civil Engineer, Italy
[3]IMAGE, Università di Padova, Italy

This paper will present a numerical model based on COMSOL Multiphysics suited to simulate the dynamic response of a catenary mooring (or a submarine cable). In general, mooring lines are subject to a direct wave load (e.g. drag, inertia) in addition to the movement of the vessel to which they are linked. Tests were carried out at the wave flume of the Maritime Laboratory of IMAGE Department, ...

3D FEM-analysis of a Micromachined Wind Sensor Based on a Self-heated Thermistor Array

[2]Institute of Sensor and Actuator Systems, Vienna University of Technology, Vienna, Austria

We present COMSOL-based analyses and design optimizations of a micromachined wind sensor. The sensor relies on eight germanium thermistors embedded in a thin silicon nitride membrane, where two orthogonally arranged ensembles, each consisting of four thermistors, are connected to form a double Wheatstone-bridge. In operation, each bridge is supplied by a constant current and the self-heating of ...
