Air curtains used for separating smoke free zones in case of fire

The aim of thise paper is to take the advantage of CFD application in calculating, optimising, and designing air curtains used to separate smoke free zones in case of fire. Properly designed air curtain produces a pressure drop which forbids transversal flow through the opening. Most air curtains are tested on scaled down models which are difficult to extrapolate. The intention of this paper is to present the possibilities of CFD while designing air curtains used in fire safety engineering.
