AbstractThis paper describes a method for simulating the natural wind boundary layer in a conventional, short working section, aeronautical wind tunnel. The boundary layers, which may be as thick as one-half of the working section height, are generated by spires at the working section inlet. This approach has been used to measure mean wind pressures and pressure spectra on a model of a tall building in downtown Montreal. The same measurements have been repeated using the long roughness fetch technique for boundary layer generation and the results from the two methods are compared. An extensive program of full-scale measurements of wind pressures has been completed on the Montreal building. These data are reviewed and a comparison is made between full-scale and model values of mean wind pressures and pressure spectra.
