ANALYSIS OF A THREE-DIMENSIONAL VENTILATION FLOW: EXPERIMENTAL VALIDATION ON A WATER SCALE MODEL OF NUMERICAL SIMULATIONS

Abstract

Laboratory and numerical experiments were conducted in order to study the flow within an isothermal parailelepipcdic test room. The air is injected through a complex diffiiser (made of 84 nozzles) near the ceiling and is evacuated through a rectangular exit just below the inlet. Measurements were performed on a hydraulic model at 1/6 scale. The parameters were determined according to a Reynolds similitude. Both laser Doppler anemometry and flow visualization were used. Numerical simulations were carried out using the EOL-3D software developed at the Institute National de Recherche et de Sécurité. A comparison between experimental results and numerical predictions is presented.
