The geometry of swirl diffusers plays a primary role in the effective airflow distribution. In this work, the airflow of swirl diffusers has been studied with the use of the Particle Image Velocimetry (PIV) method in order to analyse the mean swirling air flow and the geometry influence on the results. The presented laboratory model was a simplification of the real system and was made in the geometric scale 1:10. Based on the measurements, the velocity flow field was evaluated and the range of the effective operation of the diffuser in the axis of the flow was determined. This will enable a better definition of the conditions of ventilation in buildings and will help in the design of more efficient diffusers. Also, it will help in a better understanding of the swirl diffuser airflow and the physical effects of the key geometric features.
