抜粋

Time-averaged wind loads on cantilevered circular cylinders at high Reynolds numbers have been studied in a wind tunnel by using rough-walled models. The primary purpose of this study is to construct models of the aerodynamic coefficients for full-scale application. Measurements were made of the wind pressure distributions on the cylinder surface. Data gathered from a number of experiments concerned with this subject are also reviewed. The results indicate that the aerodynamic coefficients in the transcritical regime are functions primarily of the aspect ratio and the surface roughness of the cylinder. For the drag coefficient and the circumferential pressure distribution, quantitative descriptions of their behavior are provided as functions of these two factors.
