On acoustical resonance in tube arrays part I: Experiments

Flow Periodicity and Acoustic Resonance in Parallel Triangle Tube Bundles

“…As mentioned earlier, the observed acoustic behaviour of parallel triangle arrays is found to be similar to that of in-line arrays, which has been investigated in some detail by Ziada et al (1989) and OengoK ren & Ziada (1992a). This similarity seems to stem from the fact that both array patterns allow the #ow to proceed freely along the #ow lanes between the tube columns.…”

Vorticity shedding and acoustic resonance in tube bundles

“…Although this excitation has been recognized since the 1950's, its cause has been disputed in the literature (Owen, 1965). Recent studies have shown clearly that it results from vortex shedding from the tubes (Weaver, 1993;Ziada et al, 1989aZiada et al, & 1992. In this paper, normal triangle and rotated square patterns will be discussed first because their flow characteristics have some similarities.…”

An in-Depth Study of Vortex Shedding, Acoustic Resonance and Turbulent Forces in Normal Triangle Tube Arrays

“…It has been reported by many researchers that the flow in staggered tube arrays is dominated by periodic flow activities at multiple frequencies (Z [ ukauskas & Katinas 1980;Weaver et al 1986;Ziada et al 1989a;Price & Zahn 1991). More recently, Weaver Lian & Huang (1993) and Polak & Weaver (1994) studied the phenomenon of vorticity shedding in rotated square and normal triangle arrays.…”
