Generation of vortex noise in flow past a profile in a channel
Abstract
The paper deals with an experimental investigation of sound generation by vortex shedding from plates of various profiles in a channel of rectangular cross section (150 x 50 mm). The influence of the plate profile, Mach number (0.05 to 0.3), and pressure ((1.05 to 2.5) x 10 to the fifth) on the frequency and amplitude of the generated oscillations was investigated. The results obtained were interpreted qualitatively.
