Strouhal number of bridge cables with ice accretion at low flow turbulence

Popis výsledku v původním jazyce

The paper concerns with the method and results of wind tunnel investigations of the Strouhal number (St) of a stationary iced cable model of cable-supported bridges with respect to different angles of wind attack. The investigations were conducted in theClimatic Wind Tunnel Laboratory of the Czech Academy of Sciences in Telč. The methodology leading to the experimental icing of the inclined cable model was prepared in a climatic section of the laboratory. The shape of the ice on the cable was registered by a photogrammetry method A section of an iced cable model with a smaller scale was reproduced with a 3D printing procedure for subsequent aerodynamic investigations. The St values were determined within the range of the Reynolds number (Re) between 2.410^4 and 16.510^4, based on the dominant vortex shedding frequencies measured in the wake of the model. The model was oriented at tree principal angles of wind attack for each of selected Re values. The flow regimes were distinguished f
