Final report

  
Results in Hungarian
A projekt eredményei, melyek fokozott hatásfokú, mérsékelt zajú, megbízható új axiális ventilátorok ipari perspektíváit mutatják fel, az alábbiak. a) Kis Reynolds-számú ívelt lemezlapátok felhajtó- és ellenálláserő-tényezőit tartalmazó empirikus adatbázis megalapozása, aerodinamikai szempontból hatékony, versenyképes új ventilátorok tervezhetősége érdekében. b) Félempirikus modell kidolgozása a profil-örvényleváláshoz kötődő zaj és rezgés tervezési modellezésére. c) Egyszerű, de hatékony minimál-modell kifejlesztése a lapátnyomokra és terjedésükre: a lapátrácsok egymásra hatásának, és az ehhez kötődő tonális zaj sávkiszélesedésének tervezésben történő jellemzésére; valamint az örvénymozgás leírására, az örvényzaj tervezési modellezésének támogatása érdekében. d) Hatékony és gazdaságos megoldások kifejlesztése csőbe épített ventilátorok gyűrű alakú mikrofontömb-elrendezéseire és nyalábformálási módszereire, eset-specifikus, testreszabott zajforrás-tanulmányok és zajcsökkentési tesztek érdekében. e) Az akusztikailag átlátszó „vizsgáld a csövön keresztül” elrendezés kísérleti adatbázisának kiterjesztése: csövön belüli mikrofontömbös vizsgálatok, valamint az Ipar 4.0-ban alkalmazandó ventilátor-állapotfelügyelet támogatására. f) Mérési és számítási adatok feldolgozási és kiértékelési technikáinak továbbfejlesztése, a keskeny- és szélessávú ventilátor zajforrások mélyebb megértése és osztályozása, valamint az áramlási jelenségekkel való kapcsolataik feltárása érdekében.
Results in English
The results of the project, offering industrial perspectives toward new, high-efficiency, low-noise, reliable axial fans, are as follows. a) Establishment of an empirical database on the lift and drag of low-Reynolds-number cambered plate blades; enabling the design of aerodynamically efficient, competitive new fans. b) Elaboration of a semi-empirical model; as a design tool for consideration of dominant frequency of fan noise and blade vibration caused by profile vortex shedding. c) Development of a minimal model for the blade wakes and their dispersion; for straightforward but effective design characterisation of blade row interaction as well as frequency broadening of the related tonal noise; and for description of vortex motion, enabling the design modelling of vortex-induced noise. d) Development of effective and economical solutions for annular phased array microphone (PAM) installations and beamforming methods, for case-specific, comprehensive examination of noise sources, and for testing noise-reducing methods, in ducted fans. e) Expanding the experimental database on the acoustically transparent „observe-through-a-duct” layout, serving as a means for in-duct PAM studies, and for fan condition monitoring in Industry 4.0 applications. f) Elaboration of advanced processing and evaluation techniques on experimental and computational data, for deeper comprehension of narrow- and broadband acoustic sources of fans, and for discovering their relationships to flow phenomena.
