Abstract: The effectiveness of the use of different strake positions to control vortex asymmetry was investigated. The experiment was performed in an open-loop wind tunnel with a rectangular test section, operating at a freestream velocity. The result shows that a strake placed at the tip of the nose can cause a significant reduction in the side force acting on the ogive cylinder. The oil surface flow visualization which that the presence of a strake alters the position and the shape of the separation line. It was observed that without the strake, the separation line originates slightly downstream of the tip, whereas with the strake placed at the tip, it appears to start at the tip.
