CFD-modelling of active displacement air distribution.

Author(s) : KOSKELA H.

Summary

Active displacement air distribution is a relatively new low-impulse method, which is mainly used in large spaces such as industrial halls. The supply air is distributed with nozzle ducts, which are placed above the occupied zone. The air velocity in the nozzles is high, but it is quickly reduced due to circulation between the jets. The supply air mixes with the room air in the near zone of the duct. A simplified model for the nozzle duct inlet device is needed for CFD-modelling of room air flow patterns. The purpose of the study was to develop and test such a model.
