SD-95-14-2 -- Airflow in a World Exposition Pavilion Studied by Scale-Model Experiments and Computational Fluid Dynamics PDF

The ventilation design concept, model experiment results, two-dimensional computational fluid dynamics simulation, and on-site measurements are presented for the Danish Pavilion project at the 1992 World Exposition in Seville. Gives a short project history for the building and the ventilation system. The air conditioned restaurant and exhibition hall have a floor area of 450m² (4,850 ft²) and a mean height of 18m (59 ft). it is ventilated by a "cooling wall" with a height of 12m (39 ft). The flow from the cooling wall is similar to the flow in a room with displacement ventilation. Scale-model experiments and computational fluid dynamics simulations indicate a velocity level in the occupied zone of approximately 0.6 m/s (approx. 120 fpm) and the results are confirmed by on-site measurement in the exhibition hall. It is shown that even a simplified two-dimensional flow simulation will give valuable information to be used in the design procedure.
