Abstract: John Fitzpatrick was Professor of Mechanical Engineering at Trinity College Dublin, from 1994 to his passing away in Sept. 2012. The utter sadness of his death at the age of 63 was deeply felt by his family, friends, ...

Abstract: Flowexcited resonances of acoustic trapped modes in ducted shallow cavities are reviewed in this paper. The main components of the feedback mechanism which sustains the acoustic resonance are discussed with particular ...

Abstract: The excitation mechanism of acoustic resonances has long been recognized, but the industry continues to be plagued by its undesirable consequences, manifested in severe vibration and noise problems in a wide range of ...

Abstract: Self-sustaining oscillations of flow over ducted cavities and in corrugated pipes are a known source of tonal noise and excessive vibration in industrial applications. Corrugated pipes can be modeled as a series of ...

Abstract: Flow over ducted cavities can lead to strong resonances of the trapped acoustic modes due to the presence of the cavity within the duct. Aly and Ziada (2010, “FlowExcited Resonance of Trapped Modes of Ducted Shallow ...

Abstract: The results of an experimental investigation of the flow perturbations associated with tube vibrations along the interstitial flow path are presented. A parallel triangular tube array consisting of seven rows and six columns ...

Abstract: The maximum skin friction and flow field are experimentally measured on a planar impinging gas jet using oil film interferometry (OFI) and particle image velocimetry (PIV), respectively. A jet nozzle width of W = 15 mm, ...

Abstract: The maximum impingement plate skin friction and flow field is measured for an acoustically forced planar impinging gas jet using oil film interferometry (OFI) and particle image velocimetry (PIV), respectively. The study ...
