Abstract

Experiments were conducted to investigate the acoustic forcing of a thin aluminum plate by low-speed jets. The Mach numbers of the jets were 0.1 and 0.2. The results indicate that the structural response is due to two causes. One is the low-frequency forced excitation of the thin plate due to the leapfrogging interaction of ring vortices. The other one is the natural frequency response at a higher frequency due to turbulent fluctuations in the jet. The former is directionally dependent while the latter is both directionally and position independent.
