So the accurate simulation of room airflows with air supplies mounted just below the ceiling requires a highlevel turbulence closure. Therefore in this paper the potential for the improvement of room airflow prediction by using different Reynolds stress models and a new nonlinear eddy viscosity turbulence model are discussed. For this purpose detailed three dimensional PIV measurement results of the velocity distribution and the Reynolds stress in a symmetrical model room are compared with the calculations using different turbulence models.eninfo:eu-repo/semantics/openAccesshttps://creativecommons.org/licenses/by/4.0/Konferenzbeitrag
