Abstract
The aim of this work is to contribute to the progress in the determination of indoor airflow in buildings and to explore the possibility of coarse grid CFDsimulations for room airflow in building energy programs. To do so, a three dimensional ventilated cavity with mixed convection is simulated with different LES models and different meshes to see their influence on the numerical results. The Rayleigh number for this case is 2.23 x 109 and the Archimedes number is 0.036. This case is, to a certa...
