Experimental results and two-dimensional computer code predictions are shown which illustrate the internal air flow inside model rooms when loaded externally by air shock waves in a 5-20 psi range. Stagnation and side-on fill pressure records are presented for three-dimensional models which indicate that flow patterns similar to those observed in the two-dimensional study are present inside the three-dimensional models. Baffles were placed inside the entrances of the models which re-directed the air flow to positions off the entrance centerline and gave more safe floor area.
