Zvichienderana nek-ε (k is turbulent kinetic energy, ε is turbulence dissipation rate) turbulence model, bepa rino rinoshandisa inlet mass flow rate uye outlet static pressure semamiriro ekuverenga manhamba kumisikidza modhi yekufananidza yenhamba yendima yemukati yekuyerera. iyo diaphragm valve. Kururama kwacho kwakaongororwa nemiedzo. Pamusoro pechikonzero ichi, muenzaniso wakashandiswa kuongorora maitiro ekuyerera kwemukati uye kumanikidzwa kwemunda kugoverwa kwevhavhavha pasi pemamiriro akasiyana-siyana ekuyerera (2.787kg / s kusvika 33.273kg / s), uye huwandu chaihwo hwehuwandu hwekuyerera kwemukati uye valve. muviri kurasikirwa musoro zvakasimbiswa. ukama. Zvigumisiro zvinoratidza kuti: 1) Numerical simulation inogona kufanotaura zviri nani kurasikirwa kwemusoro wemuviri wevhavha pasi pemamiriro akasiyana-siyana ekuyerera. Kana iyo inlet inoyerera iri 5.546kg/s, 11.091kg/s uye 16.637kg/s zvichiteerana, mhosho pakati pebvunzo nenhamba yekuenzanisa inongova -6.433%, 4.619% uye 7.264%. 2) Pasi pemamiriro ekugara achiyerera, kubva pakupinda kuenda kune yekubuda, iyo static kudzvanywa muchiteshi chekuyerera kazhinji inoratidza kuderera kwemaitiro. Mukati memuviri wevharuvhu, nzira yekuyerera inodzikira nekuda kwekuvharika kwevhavha sill uye kuyerera kunorova diaphragm kukonzera kutsauka. Yakakura static pressure gradient. 3) Mushure mekunge mvura ichiyerera ichipfuura nemugero rakamanikana pavhavha sill, iri pachena cavitation zone inoumbwa pasi pemvura yevharuvhu, ichiperekedzwa neimwe backflow phenomenon. Iyo cavitation zone kuzasi kwemuviri wevharuvhu inonyanya kuoneka mune 1/3 fluid domain kubva pakubuda. , sezvo inlet inoyerera ichiwedzera, iyo vortex yakadzika yemuviri wevhavha inowedzera zvakanyanya uye chiitiko chekudzoka chinowedzera kukosha, asi chiyero chenzvimbo yekudzokera shure hachiwedzere zvakanyanya. 4) Kubva pakurongeka kwechokwadi chemuenzaniso, muenzaniso wakashandiswa kuenderera mberi nekuongorora maitiro emukati ekuyerera uye kumanikidzwa kwemunda kugoverwa kwemuviri wevhavha pasi pe18 inlet kuyerera kwemamiriro ezvinhu, uye kusimbisa hukama hwehuwandu pakati pe inlet mass flow rate Q uye vharafu muviri kurasikirwa nemusoro △P , kana iyo inlet mass kuyerera Q ichibva 2.787kg/s kusvika 15.428kg/s uye nhamba yeReynolds inobva 37927 kusvika 215984, equation yakakodzera ndeiyi △P=2076.31Q-7567.49, R2=0.964; iyo inlet mass kuyerera inobva pa17.141kg/s kusvika 33.273kg/s, iyo yakafanira equation apo nhamba yeReynolds ichibva pa240097 kusvika 467009 iri △P=5688.02Q-67317.39, R2=0.993, iyo inopa hydrlic base yepombi yekudiridza network.
