Evaluation of shelter ventilation by model tests. Option 2. Final report, August 1983-September 1984

Wind tunnel tests were carried out using models of fallout shelters to determine correlations between shelter ventilation rate, area and distribution of wall openings, wind speed and its direction relative to the orientation of the shelter. Models of bermed shelters with five different opening configurations were used. A simple correlation was formulated between the shelter ventilation rate, the total area of windward openings, the ratio of leeward to windward opening areas and the velocity of the approach wind. Results were compared with those projected from available correlations for general type buildings. Originator provided keywords include: Flow visualization and Relative wind angle.
