Detailed simulation of pressures in separated/reattached flows

Abstract Mean and fluctuating pressure coefficients from four wind tunnel roughness configurations are investigated for three sets of pressure taps on the roof of a 1:50 scale model of the Texas Tech Wind Engineering Research Field Laboratory experimental building, and compared with the field data where possible. Pressure coefficients obtained from a set of pressure taps under the corner vortex are also investigated and presented. This investigation also includes the study of extreme pressure peaks and their duration, for individual pressure taps and area averaged pressures. Flow simulation requirements for wind tunnel experiments are introduced, which are considered essential for a realistic assessment of wind loads in critical areas.
