Experimental Determination of the Drag Coefficients and Strouhal Numbers of a Port Crane Boom Girder Section
Abstract eng: This work reports the drag coefficients (Cd) for three wind directions measured in low turbulence flow and in turbulent flow with characteristics of the atmospheric boundary layer wind, and the Strouhal numbers (St) of an approximately trapezoidal flanged section, used in the boom girder of a 100 m high port crane. These experimental results were obtained at the Boundary Layer Wind Tunnel of the Dept. Aeronautica at the Universidad Nacional de La Plata, in the range of Reynolds numbers between 30000 and 180000. The drag coefficients in the three studied directions showed a reduction for turbulent flow. Further measurements were carried out for the model with an inclination of 80º relative to the flow direction, the position of the crane boom when out of service, giving practically the same drag coefficients.
