Résumé:
This thesis concerns a numerical study of the simple swirling air jet, applied to thermal comfort
in residential premises. The objective of this work is to improve the efficiency of air diffusion in the
occupied zone at a lower cost, by a passive means of control. Two turbulence models were tested to
improve the predictions of the turbulence models: the Smagorinski-Lilly (LES/S-L) model and the
Wall-Adapting Local Eddy-Viscosity (LES/WALE) model to choose the most appropriate model for
this type of flow. The results obtained with the turbulence model (LES/S-L), agree with the
experimental results. They show interest in the characterization of this type of jet for its application to
HVAC systems (heating, ventilation, and air conditioning).
