Abstract
The aim of this paper is to take advantage of CFD application in calculating, optimizing, and designing air barriers used to separate smoke free zones in the case of fire. Properly designed air curtain produces a pressure drop which forbides transversal flow through the opening. It is hard to make a good quality CFD calculation of that kind of air curtain because of high velocity and relatively thin nozzle. Most air curtains are tested on scaled down models which are difficult to extrapolate. The author of this article performed tests in a real scale model. Tests results were used to verify chosen turbulence model. The intention of this paper is to present the comparison between CFD calculations and tests results.
