... of reverberation chambers, with no parallel or orthogonal walls, may help to avoid resonance and thus prevent large pressure fluctuations. In this paper, flow inside a scale model jet engine testing facility was studied computationally with IDDES-based CFD, and the mechanism for low-frequency, high amplitude...

...K. K. Botros; E. Clavelle; H. Satish Acoustic resonances in internal flows can cause noise, vibration, and even equipment damage. One geometry prone to acoustic resonance is a deadleg at the point where the main flow turns into a side branch. Here, we report experimental and computational fluid...

...S. C. Li; Z. G. Zuo; S. H. Liu; Y. L. Wu; S. Li This article deals with a phenomenon named as cavitation resonance. Cavitation-associated pressure fluctuations in hydraulic systems affect their design, operation, and safety. Under certain conditions, the amplitude of a particular component...

.... The spectral character of these signals was analyzed and the pressure levels and dominant frequencies determined. This study indicates that large changes in the pressure level occur as L / W varies from 0.115 to 0.682. A state of fluid dynamic resonance was observed at L/W=0.137 and fluid–acoustic resonance...
