...S. L. Finnegan; C. Meskell; S. Ziada Aeroacoustic resonance of bluff bodies exposed to cross flow can be problematic for many different engineering applications and knowledge of the location and interaction of acoustic sources is not well understood. Thus, an empirical investigation...

... of flexural resonance, which creates pipe stresses significantly in excess of the stresses expected from a slowly applied, or static, pressure loading. To investigate flexural resonance, vibration equations were successfully compared to available experimental results. At shock velocities, the maximum hoop...

... excitation mechanism. Vibration response, excitation forces, and fluctuating properties of two-phase flow were measured over a wide range of flow conditions. The results show that the observed vibrations are due to a resonance phenomenon between periodic momentum flux fluctuations of two-phase flow...

... a range which caused resonant vibrations of the gas in the vessel. A receiving transducer measures the amplitude of the resultant vibration at the vessel surface and reveals the resonant frequency of the gas at peaks in the amplitude of the sweep. The resonant frequency obtained depends upon...

... and emphasizes the wave resonance tuning approach to defect analysis and improved penetration power. The wave tuning exercise is illustrated with a defect cluster detection experiment in a pipe followed by some analytical and experimental tuning of guided waves in a coal tar coated pipe. Excellent results were...
