Selected results of experimental studies on the effect of icing on the aerodynamics of bridge cables

Popis výsledku v původním jazyce

This paper presents an outline of the results of experimental studies on the effect of icing on the aerodynamics of cables of cable-supported bridges. The following were carried out in the framework of these studies: (1) the experimental icing process of the bridge cable model with a circular cross-section in the climatic chamber of the wind tunnel, (2) the optical visualization PIV (Particle Image Velocimetry) in the near-wake behind the ice-accreted cable model, (3) the Strouhal number investigations, and (4) the investigations of the mean aerodynamic force coefficients. Aerodynamic tests were carried out at average free stream velocities within the range of 3–25 m/s, corresponding to the Reynolds number values within the range of 2·104–17·104. The average turbulence intensity during the investigations was about 3% and 12%. The test results for the ice-accreted bridge cable model were compared with those obtained for a circular smooth cylinder in similar flow conditions.
