Vortex Shedding by Blunt/Bluff Bodies at High Reynolds Numbers. Volume 3. Cubes

Abstract

This report documents the analysis of vortex shedding data collected by the Phillips Laboratory at the U.S. Air Force Academy Subsonic Wind Tunnel facility. The analysis is primarily of the power spectrum of the vortex shedding as seen in the force and moment coefficient power spectra. The shedding frequencies as seen in the power spectra are used to analyze for the Strouhal number. The analysis suggests that shape and orientation in the wind field have an effect on the shedding of vortices.... Vortex shedding, Vortices, Aerodynamic forces, Coefficients, Drag, Strouhal number.
