Wind tunnel study of a cone-like shaped roof: Reynolds number effects

This paper describes the results of wind tunnel tests performed on a cone-like shaped roof characterised by multiple curved surfaces. Surface pressure measurements were carried out by high-frequency scanners. In particular, Reynolds number and surface roughness effects on the mean pressure distribution and on its unsteady components have been analysed. Methodologies were found in order to validate the wind tunnel wind load measures performed on scale models having the typology of building roofs with curved surfaces.
