Vpliv geometrijske oblike poenostavljenega modela ventila na nastanek hidrodinamičnega hrupa = Influence of the simplified valve model geometry on hydrodynamic noise generationPrek, Matjaž ; Novak, Peter, 1937-2022Meritve akustičnih karakteristik zapornih organov za kapljevino - predvsem vodovodnih armatur - pogosto (praviloma) temeljijo na meritvah ravni zvočnega tlaka v zraku. S tem ni omogočena neposredna ... določitev parametrov, ki bi enopomensko popisali akustične lastnosti armature. Le z metodo neposrednega merjenja zvočnega tlaka v kapljevini je omogočen boljši vpogled v mehanizem nastanka in širjenja hrupa. Zaradi vpliva merilne proge na karakteristiko merjene veličine je pri takih meritvah treba definirati prenosno funkcijo, ki tvori s karakteristiko vira hrupa sklenjeno zanko. S spreminjanjem razmer se spreminjajo tudi vrednosti parametrov prenosne funkcije. Te informacije pa so, poleg določevanja karakteristik hrupa , uporabne tudi kot informacija pri izbiri ukrepov, ki zmanjšujejo emisijo hrupa ter njegovo širjenje po vodnem stebru. Tako določene akustične karakteristike armature omogočajo uporabo hidroakustičnih modelov, s katerimi lahko v grobem določimo razmerja med hidravličnimi in akustičnimi razmerami. Prikazani so rezultati eksperimentalno določenega vpliva dolžine in premera natočne cevi na akustično karakteristiko modela ventila. Pri analizi soodvisnosti vpliva geometrijskih parametrov je bila ugotovljena funkcijska odvisnost, ki smo jo definirali kot vitkost.Source: Strojniški vestnik = Journal of mechanical engineering. - ISSN 0039-2480 (Letn. 45, št. 3, 1999, str. 99-108)Type of material - article, component partPublish date - 1999Language - slovenian, englishCOBISS.SI-ID - 3141403
