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

Objective of this contribution is to show how to implement the Mild Slope Equations with COMSOL Multiphysics. These equations are commonly used to study the propagation of waves in harbors. Some interesting features are presented, namely the use of weak terms (used for the modelling of the source term); the evaluation of a smooth phase gradient from the complex dependent variable; a robust ...

Relief patterning of the surface of microchannels has been actively pursued as a method of promoting mixing in systems with a low Reynold’s number (<<100). In this work, we explore, by using the COMSOL Multiphysics package and its Chemical Engineering Module, the possibility of enhancing the mixing quality of two fluids in a microchannel with a non-periodic fractal pattern of ridges ...

One of the major applications for dielectrophoresis is the selective trapping and fractionation in lab-on-a-chip devices. Nevertheless, many-particle effects due to high concentrations of biological material around electrodes can cause a rapid decrease of trapping efficiency in dielectrophoretic devices. In this contribution we present a new approach based on a drift-diffusion dynamics to study ...

The paper attempts to give a contribution to the dynamic analysis of musical instruments. A multidisciplinary approach oriented to the study of mechanical, structural, vibratory and acoustical phenomena related to stringed instruments is discussed. The case study focused in this paper concerns the violins family: the geometry and the vibratory propagation of this instrument is very complicated to ...

Structural, morphological and ground deformation studies suggest that the eastern flank of Mt. Etna (eastern Sicily) is spreading seaward. According to the deep-seated spreading model, both the volcanic edifice and its uppermost basement are spreading eastwards because of magma inflation processes related to a dike complex located at a depth between the summit craters and the Valle del ...

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 ...

Monitoring of indoor CO2 concentration is of particular interest to detect room occupancy in order to optimise power consumptions of building. One technological approach is to use optical detection using specific absorption lines of CO2 molecules in the infrared domain close to 4.2 μm. Key features for a wider use in public and private buildings are power consumption and price. Such optical ...
