Numerical Simulation of Three-Dimensional Aerodynamic Behavior of a Yawed, Inclined Circular Cylinder

The effects of the angle of the cylinder to the flow on characteristics of the flow and the associated forces were also examined in this study. As yaw angle increases, the peak frequency of Cy deviates from the prediction by the Cosine Rule. The dominant frequency of Cx has a relatively low-frequency component and increases with yaw angle, but it cannot be predicted by the Cosine Rule. The comparison results indicate that the three-dimensional characteristics of the forces cannot be precisely explained by a quasi-two-dimensional approximation, such as the Cosine Rule.
