Effect of cylinder eccentricity on separating shear layers at subcritical Reynolds numbers
Abstract
Location of the separating shear layers associated with a family of elliptic cylinders is studied in the Reynolds number range of 20,000-200,000 using a semi-focusing Schlieren system in conjunction with high-speed photography. The experimental results are compared with the analytical predictions using the Goertler series approach as well as the measured minimum pressure points. In general, the correlation is quite satisfactory.
