Effects of corner cuts and angles of attack on the Strouhal number of rectangular cylinders

Chang- Koon Choi and Dea-Kun Kwon

Abstract

An investigation into the effect of corner cuts on the Strouhal number of rectangular cylinders with various dimensional ratios and various angles of attack is described. The Strouhal number given as a function of corner cut size is obtained directly from the aerodynamic behavior of the body in a uniform flow through a series of wind-induced vibration tests. For a quick verification of the validity of the Strouhal numbers obtained in this way, they are compared with the approximated the Strouhal numbers based on Shiraishi

Key Words

Strouhal number; corner cut; angle of attack; wind tunnel experiment; rectangular cylinder.
