Abstract This study deals with the effects of wind turbulence on the mean aerodynamic drag, lift and moment coefficients of a stationary ice-accreted section model of a bridge cable for different wind angles of attack. The experiments were conducted in the Reynolds number range between 2.5·104 and 1.36·105. While the yawed/inclined cable model was experimentally iced in a climatic wind tunnel, the development of the ice shape was registered using photogrammetry. Later on, the ice-accreted model was reproduced on a smaller scale via three-dimensional printing. For the model in cross-flow, a series of wind tunnel tests were performed in low and moderately turbulent flow conditions with turbulence intensities of 3% and 12%, respectively. The obtained results were compared with those obtained experimentally for a circular smooth cylinder. The principal finding is that the flow turbulence significantly reduces the drag coefficient.

中低湍流风条件下结冰桥索的气动力系数

摘要 本研究研究了风湍流对不同风攻角下桥索固定结冰截面模型的平均气动阻力、升力和力矩系数的影响。实验在雷诺数范围在 2.5·104 和 1.36·105 之间进行。当偏航/倾斜电缆模型在气候风洞中进行实验结冰时，冰形状的发展是使用摄影测量记录的。后来，通过三维打印以较小的比例复制了积冰模型。对于横流模型，在湍流强度分别为 3% 和 12% 的低湍流和中等湍流条件下进行了一系列风洞试验。将获得的结果与圆光滑圆柱体实验获得的结果进行比较。
