The effects of roof geometry and wind direction were isolated by making the wind-tunnel flow representative of natural winds over very flat, open terrain. This flow simulation was accomplished by placing vortex generators at the entrance to the wind-tunnel test section. Mean pressures, root-mean-square values of the fluctuating pressures, and instantaneous peak pressures were measured at 11 preselected locations on the model's roof for 24 wind directions. A secondary purpose of the study was to determine the effects of an upwind fence on the roof pressures.technical reportsengCopyright and other restrictions may apply.
