Naturally ventilated geothermal foundation modeling. 6th International Conference on Building Physics for a Sustainable Built Environment
Résumé
This work is concerning the modeling of a heat and mass transfer within a new kind of Canadian well, a geothermal foundation, and its coupling with a solar chimney. The foundation model is based on a 3D finite volume method. A long term simulation is necessary, aiming to precisely understand the behaviour of this combined system. Since this model requires high computational resources, we propose to use a domain decomposition technique and the balanced realization reduction method to speed up computational time. The studied case shows this system seems to be relevant to supply cold air to buildings during summer.
