Ukurikije k-ε (k ni imbaraga za kinetic imbaraga za kinetic, ε nigipimo cyo gukwirakwiza imivurungano) moderi yimivurungano, iyi mpapuro ikoresha umuvuduko wimibare winjira hamwe numuvuduko uhagaze nkumubare wimibare kugirango ushireho urugero rwikigereranyo cyumubare wimiterere yimbere yimbere diaphragm valve. Byagenzuwe neza. Hashingiwe kuri ibyo, icyitegererezo cyakoreshejwe mu gusesengura ibiranga imigendekere yimbere n’ikwirakwizwa ry’umuriro ukwirakwiza umubiri wa valve mu bihe bitandukanye byinjira (2.787kg / s kugeza 33.273kg / s), nubunini nyabwo bwikigereranyo cyinjira na valve guta umutwe kumubiri byashyizweho. isano. Ibisubizo byerekana ko: 1) Kwigana kumibare birashobora guhanura neza gutakaza umutwe wumubiri wa valve mubihe bitandukanye. Iyo umuvuduko winjira ari 5.546kg / s, 11.091kg / s na 16.637kg / s, ikosa rigereranijwe hagati yikizamini no kwigana imibare ni -6.433%, 4.619% na 7.264%. 2) Mugihe cyimiterere ihora yinjira, kuva kumurongo ugana hanze, umuvuduko uhagaze mumuyoboro utemba muri rusange werekana kugabanuka. Imbere yumubiri wa valve, umuyoboro utemba uragabanuka kubera inzitizi ya sili ya valve kandi imigezi ikubita diafragma kugirango itere gutandukana. Umuvuduko munini uhagaze. 3) Nyuma yuko amazi atemba anyuze mumuyoboro muto kuri sili ya valve, agace kagaragara ka cavitation kagizwe hepfo yumubiri wa valve, iherekejwe nikintu runaka cyo gusubira inyuma. Agace ka cavitation kumanuka kumubiri wa valve kugaragara cyane muri 1/3 cyamazi yaturutse hanze. , uko urujya n'uruza rwiyongera, vortex hepfo yumubiri wa valve iba ikomeye cyane kandi ibintu byo gusubira inyuma bigenda bigaragara cyane, ariko urugero rwahantu rwinyuma ntirwiyongera cyane. 4) Hashingiwe ku kugenzura neza kwicyitegererezo, icyitegererezo cyakoreshejwe mu kurushaho gusesengura imiterere yimbere yimbere nigabanywa ryumuriro wikwirakwizwa ryumubiri wa valve munsi yimiterere ya 18 yinjira, no gushyiraho isano iri hagati yumuvuduko mwinshi winjira Q na the guta umutwe kumubiri △ P, mugihe inlet yinjiza Q kuva kuri 2.787kg / s kugeza 15.428kg / s naho numero ya Reynolds kuva kuri 37927 kugeza 215984, ikigereranyo gikwiye ni △ P = 2076.31Q-7567.49, R2 = 0.964; ubwinshi bwinjira bwinjira kuva kuri 17.141kg / s kugeza 33.273kg / s, ikigereranyo gikwiye iyo nimero ya Reynolds kuva kuri 240097 kugeza 467009 ni △ P = 5688.02Q-67317.39, R2 = 0.993, itanga ishingiro ryerekana kubara hydraulic. y'umuyoboro wo kuhira.
