Abstract
Experiments are presented for a 1:50 scale model of the Wind Engineering Research Field Laboratory (WERFL) experimental building located on the Texas Tech University campus in Lubbock, Texas. The model was immersed in three different boundary layers generated in the Clemson University wind tunnel. These flows closely simulated the lowest 50 m of the atmospheric boundary layer at the WERFL site. The tests were conducted in order to study the velocity-pressure relations for the near-field and far-field flows. Observations were made with the flow normal to the roof edges for roof pressures along a line parallel to the flow, and for the roof-corner pressures with oblique azimuth angles. Additional results to study the far-field relation for stagnation flows were obtained in the Ruhr-University Bochum wind tunnel from a 1:350 scale model of the main building at the Eindhoven Technical University (ETU) in the Netherlands. Results of the nonlinear cross-bicoherence and linear cross-coherence between far-field and near-field velocity fluctuations and surface pressure fluctuations are discussed in detail. These coherences represent the contribution of the velocity fluctuations to the surface pressures according to Poisson's equation.
