A model of a Molten Carbonate Fuel Cell (MCFC) stack with internal reforming is presented. It describes the concentrations in the gas phase, the temperatures and the current densities in this highly integrated system. The differential equations, boundary conditions and the coupling equations used in the model are presented. A strategy to solve the system of partial differential ...
Benchmarking as Key Element of Confidence Building in Safety Assessments for Radioactive Waste Disposal
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 ...
Transient Conjugate Optical-thermal Fields in Thin Films Irradiated by Moving Sources: A Comparison between Back and Front Treatment

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 ...

Many theoretical studies concerning lava tubes focus on the thermal disturbances generated on the earth surface. Recently a solution was suggested, where a lava tube located at a great depth h in the soil, where the ratio between h to the major axis of the ellipse a is higher than 10. However, lava tubes more frequently are located at shallower depths. In this work we ...
