Vorticity shedding and acoustic resonance in an in-line tube bundle part II: Acoustic resonance

Vortex-induced cross-flow seiching in cylinder arrays

“…The qualitative equivalence between VIV and the transverse seiching in open channel flow was observed in the experimental investigations by Oengören and Ziada [10][11][12][13] on acoustic resonance in tube bundles. In these studies, which focused on the typical frequencies of the phenomenon, the existence of a lock-in region straddling the resonance condition was confirmed for the case of water waves.…”

“…26 in [12]); in these conditions the largest amplitude oscillations occur. They also found that the natural oscillation frequency is accurately predicted by the small-wave amplitude theory [10,11] where g is gravity, n is the mode of the wave oscillation, B is the channel width, and h 0 the mean flow depth. Only a few investigations have specifically addressed the issue of transverse seiching produced by an array of vertical obstacles in an open channel flow.…”

Flow Periodicity and Acoustic Resonance in Parallel Triangle Tube Bundles

“…Detailed descriptions of its geometric and #ow characteristics are given by OengoK ren and Ziada (1992b). Here, only the information essential to understand the tests of this study will be repeated.…”

Vorticity shedding and acoustic resonance in tube bundles

“…In general, the investigated bundles will be classified into small, medium and large tube spacings. The details of the experimental techniques used in this study can be found in Ziada & Oengoeren (1992, 1993, 2000 and Oengoeren & Ziada (1992a, 1992b, 1998.…”
