Emphasis is on the fluid-elastic modeling within a time-domain nonlinear framework, as well as on the stabilizing effect of impacts on the fluid-elastic coupling forces. Theoretical computations of the linear and vibro-impacting regimes of a flow-excited cantilever test tube, within a rigid 3\u00d75 square bundle, are based on the experimentally identified fluid-elastic coupling force coefficients and turbulence spectrum. Computations are then compared with the experimental vibratory responses, enabling a full validation of the modeling approach. Furthermore, interesting conclusions are drawn, concerning: (a) the energy balance between sources and sinks, for a vibro-impacting tube subjected to fluid-elastic forces; (b) the dependence of the vibration response frequency on impacts at the loose supports, and their effect on the nonlinear re-stabilization of fluid-elastically unstable tubes. Details on the following aspects are reported in the paper: (1) Numerical modeling of the fluid-elastic coupling forces for time-domain computations; (2) Experimental identification of the fluid-elastic coupling coefficients; (3) Computations and experiments of both linear and vibro-impacting responses under the combined action of turbulence and fluid-elastic coupling; and (4) Energy aspects of the vibro-impacting fluid-elastically coupled tube responses.<\/jats:p>","DOI":"10.1115\/fedsm-icnmm2010-30071","type":"proceedings-article","created":{"date-parts":[[2011,3,8]],"date-time":"2011-03-08T18:34:50Z","timestamp":1299609290000},"page":"395-407","update-policy":"http:\/\/dx.doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":0,"title":["Vibro-Impact Experiments and Computations of a Gap-Supported Tube Subjected to Single-Phase Fluid-Elastic Coupling Forces"],"prefix":"10.1115","author":[{"given":"Philippe","family":"Piteau","sequence":"first","affiliation":[{"name":"Commissariat a` l\u2019Energie Atomique, Gif-sur-Yvette, France"}]},{"given":"Xavier","family":"Delaune","sequence":"additional","affiliation":[{"name":"Commissariat a` l\u2019Energie Atomique, Gif-sur-Yvette, France"}]},{"given":"Jose","family":"Antunes","sequence":"additional","affiliation":[{"name":"Instituto Tecnologico e Nuclear, Sacavem, Portugal"}]},{"given":"Laurent","family":"Borsoi","sequence":"additional","affiliation":[{"name":"Commissariat a` l\u2019Energie Atomique, Gif-sur-Yvette, France"}]}],"member":"33","published-online":{"date-parts":[[2011,3,1]]},"event":{"name":"ASME 2010 3rd Joint US-European Fluids Engineering Summer Meeting collocated with 8th International Conference on Nanochannels, Microchannels, and Minichannels","start":{"date-parts":[[2010,8,1]]},"sponsor":["Fluids Engineering Division"],"location":"Montreal, Quebec, Canada","end":{"date-parts":[[2010,8,5]]},"acronym":"FEDSM2010"},"container-title":["ASME 2010 7th International Symposium on Fluid-Structure Interactions, Flow-Sound Interactions, and Flow-Induced Vibration and Noise: Volume 3, Parts A and B"],"original-title":[],"link":[{"URL":"http:\/\/asmedigitalcollection.asme.org\/FEDSM\/proceedings-pdf\/doi\/10.1115\/FEDSM-ICNMM2010-30071\/2735009\/395_1.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"http:\/\/asmedigitalcollection.asme.org\/FEDSM\/proceedings-pdf\/doi\/10.1115\/FEDSM-ICNMM2010-30071\/2735009\/395_1.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,1,10]],"date-time":"2020-01-10T14:37:27Z","timestamp":1578667047000},"score":1,"resource":{"primary":{"URL":"https:\/\/asmedigitalcollection.asme.org\/FEDSM\/proceedings\/FEDSM2010\/54518\/395\/338663"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,1,1]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1115\/fedsm-icnmm2010-30071","relation":{},"subject":[],"published":{"date-parts":[[2010,1,1]]}}}
