A two dimensional instationary analysis of the conjugate optical-thermal fields induced in a multilayer thin film structure on a glass substrate by a moving Gaussian laser source is carried out numerically in order to compare back and front laser treatment processes. COMSOL Multiphysics 3.4 code has been adopted to solve the combined thermal and electromagnetic problem in order to compare the ...

Benchmarking as Key Element of Confidence Building in Safety Assessments for Radioactive Waste Disposal

E. Weetjens
SCK-CEN (the Belgian Nuclear Research Centre), Mol, Belgium

Verification of the codes applied for assessment of the long-term repository safety is typically one of the quality assurance requirements demanded by regulatory bodies, in the disposal of radioactive waste. In this paper, an internationally organized benchmark exercise is presented, in which the comparison was carried out for a selection of key radionuclides. The examples presented in this ...

Metal hydrides are a widely-used method for storing and releasing hydrogen chemically under moderate conditions. This paper will present how highly dynamic metal hydride storage has been simulated and optimized using COMSOL Multiphysics. It will be shown how mass, energy and momentum balances were implemented and what boundary conditions were set to resolve various scenarios. The result of the ...

The objective of this work has been to realize a feasibility study of a cooling device for a SQUID sensor using liquid nitrogen flowing through micro channels. The design consists of an epoxy cylindrical vacuum vessel skewed by a silicon microchannel heat sink. The SQUID sensor is situated directly on top of the microchannel heat sink. The device is used at room temperature and should be able to ...
