A series of wind tunnel tests were carried out to measure drag and lift coefficients of inclined circular cylinders with artificial rivulet for later investigation on wind-rain-induced cable vibration. The axial flow effect was naturally included in the tests, compared with previous non-yawed horizontal cylinder tests. The test Reynolds number for smooth circular cylinders in uniform flow ranged from 9.38 × 104to 1.93 × 105. A special test apparatus was designed and manufactured for easy execution of measurements. The effects of artificial rivulet, its shape, and its size on aerodynamic coefficients are discussed in this paper based on wind tunnel test results. The influence of wind yaw angle, wind speed, and cable diameter is also estimated. Furthermore, the possible transformation of wind tunnel test results to the cylinders of different inclinations and yaw angles from those used in the tests is explored.
