Experimental study of smoke movement between two rooms connected by a stairwell

Abstract : Small-scale experiments were carried out to study the smoke flow induced by a pool fire, in a multi-compartment configuration, consisting of two rooms connected by a stairwell. The stairwell was equipped with removable obstacles simulating the presence of stairs, to assess their influence on the smoke flow. The experimental results highlighted the effects of the obstacles on the flow, namely the disturbance of the distribution of the temperature in the smoke inside the stairwell, and the formation of vortices below the obstacles. A comparison between the experimental data and the numerical results with the zone code CFAST was also performed in order to assess the performance of the code.
