Ulwazi ngomjovo wedizili
I-Cavitation Ngaphakathi Kwemibhobho Yomjovo Wamafutha Okucindezela Okuphezulu Okubonakalayo(INGXENYE 2)
Imibhobho yomjovo efinyeleleka ngokubona (OA) isetshenziswe ezifundweni ezimbalwa ezedlule zokugeleza kwangaphakathi kwejiyometri yomjovo womjovo otholakala ezinjinini zokucindezelwa ngomjovo oqondile.Eziningi zalezi zifundo ezedlule zenziwa ngengcindezi yomjovo ephansi kakhulu kunaleyo yomjovo wezimboni ohlobene, ngenxa yenselele yokuklama umjovo we-OA ongamelana nokucindezela okuphezulu komjovo.Ukuze kunxeshezelwe, abanye basebenzise amajiyometri enziwe ngezikali ukuze afane nenombolo kaReynolds.
Izifundo ezizame ukufinyelela ukucindezelwa komjovo okungokoqobo zizofingqwa lapha, njengoba lezi zihambisana kakhulu nomklamo owethulwe kuleli phepha, futhi ekugcineni yizona ezinembe kakhulu uma kuziwa ekukhiqizeni kabusha ukugeleza kwentshisekelo.
U-Arcoumanis et al.ihlole umthelela wokukala amajiyometri ngenkathi ihambisana nezinombolo zikaReynolds kanye neCavitation kusayizi wangempela kanye nejiyomethri ekhulisiwe[2].Bathole ukuthi izakhiwo ze-cavitation zazihlukile kumajiyometri amabili ezinombolweni ezifanayo ze-cavitation.Zombili izikali zejiyomethri zibonise i-geometric cavitation ohlangothini olungezansi lomfula we-orifice onqenqemeni olungaphezulu (nomjovo obheke phansi), kanye ne-string cavitation ekhona ngakolunye uhlangothi lwembobo ye-orifice.
Umehluko omkhulu obonwe ababhali ubangelwe umehluko wesikhathi sokuhlala kwebhamuza ekugelezeni ngenxa yobude obuhlukene be-orifice.Umjovo wesikali esikhulu wenziwe ngengilazi ye-acrylic, kuyilapho umjovo wesikali sangempela wenziwe ngenduku ye-quartz exhunywe kumzimba womjovo we-Bosch common-rail futhi uzungezwe igalari yokusekela ye-acrylic.Ucezu lwe-acrylic lwalulukhulu kakhulu kunobhobho wensimbi wokuqala womjovo.Reid et al.isebenzise isafire ukuze idale inguqulo eyenziwe lula yejiyomethri etholakala kuma-injection e-valve-covered-orifice (VCO)[3].Bathole ingcindezi yomjovo webha engu-2000 ngomklamo.Kubonakala sengathi i-orifice yakhiwa ngokubeka amapuleti esafire ohlangothini lwe-axial ngochungechunge lwezimbobo ze-thru ezakha i-geometry yokugcina.Lena kwakuyindlela ehlakaniphile yokwenza kube lula ukucutshungulwa kwezingxenye.
