Application of a hygrothermal model to predict temperature and humidity development in the VeRCoRs benchmark case

Åhs, Magnus LU orcid ; Bernstone, Christian and Gasch, Tobias (2016)
Abstract
This study presents a multiphysics model developed to predict the internal temperature and moisture development in a concrete reactor containment at an early age. The work is a part of the benchmark study, VeRCoR, provided by EDF. The model was applied on an experimental reactor containment mock-up erected in the vicinity of Paris. The 3D geometry was provided from VeRCoRs. The model includes concrete hydration, heat release, chemical moisture binding, and a moisture transport model with relative humidity as a driving potential. Results from the simulation was compared with temperature sensors located in the mock-up. The model was found to be able to predict the temperature development at early age. There was no possibility to compare the... (More)

There was no possibility to compare the relative humidity because of lack of humidity sensors. (Less)
