Airflow characteristics in the outlet region of a vortex room air diffuser

In this paper, the airflow characteristics in the outlet region of a generic vortex diffuser are experimentally and numerically investigated. A specific arrangement of tetrahedral and hexahedral cells was used in grid generation: it has been found ideal for the analysis of the room air movement due to an air diffuser.
Corresponding airflow measurements were conducted by using a three dimensional ultrasonic anemometer.
