Effect of vortex generators on the flow around a circular cylinder normal to an airstream
Abstract
Experimental investigations were carried out to examine the effect of vortex generators on the characteristics of the flow around a circular cylinder in a cross flow in the range of subcritical Reynolds numbers. The Strouhal number, the static pressure distribution, the R.M.S. values of the fluctuating pressure, the position of the separation of flow and the structure of the boundary layer have been measured. The flow patterns can be classified according to the position and the height of the generator rows, and the roughness Reynolds number. Characteristics of these flow patterns and the relationship among them were clarified.
