Measurements of fluctuating effects on a circular cylinder in a uniform flow at subcritical Reynolds number, part 2
Abstract
Spanwise correlations of the forces on two elements of a long, smooth cylinder with end plates were carried out for a range of Reynold numbers and turbulence intensities. The resulting correlation curves are presented. A theory is proposed to use these curves to calculate the lift and drag coefficients of cylinders of finite length. These coefficients have been evaluated, and are presented in graphical form. Spanwise pressure correlations have also been investigated, and their correlation curves are shown. The results apply to aspect ratios from 10 to 50, Reynolds numbers from 10,000 to 250,000, and turbulence intensities between 0.2 percent and 7.5 percent.
