Abstract: 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. It is hard to make a good quality CFD calculation of that kind of air curtain because of a high velocity and relatively thin nozzle. Most air curtains are tested on scaled down models which are difficult to extrapolate. Author of that article had done tests in a real scale model. Tests results were used to verify chosen turbulence model. The intention of this paper is to present the possibilities of CFD while designing air curtains used in fire safety engineering.
