I-Cavitation Ngaphakathi Kwemibhobho Yomjovo Wamafutha Okucindezela Okuphezulu Okubonakalayo(INGXENYE 3)

Ukuthi idivayisi ivalwe kanjani, nokuthi amapuleti agcinwe kanjani, akufakiwe emiphumeleni eshicilelwe. Izinhlobo ezimbili ze-string cavitation zabonwa: enye eyakhiwe kuma-vortices axhunywe engxenyeni yejometri eklanyelwe ukulingisa inaliti, futhi enye eyakhiwe ku-vortex exhuma izimbobo ezimbili ze-orifice.

Badock et al. ifinyelele izingcindezi eziphakeme zomjovo isebenzisa imibhobho ye-acrylic, nakuba ifana ne-Arcoumanis et al, ucezu lwalulukhulu kakhulu kunombozo womjovo wokuqala[4]. Ukutadisha ukuhlukana okuyinhloko kwesifutho ku-nozzle enjalo akunakwenzeka ngenxa yomphumela we-lensing ebusweni bezinto ezimboziwe ezilungisa ubude bezikhala ze-nozzle orifice.

Isibusiso et al. kuzuzwe ukucindezela komjovo webha engu-800 kusetshenziswa i-acrylic injector nozzle ene-off-axis orifice eyodwa[5]. Idizayini ibihlangene ngokwanele ukuvumela ukuhlukana okuyinhloko kwesifutho esiphuma endaweni ephuma emlonyeni womlomo ukuze kufundwe ngesikhathi esisodwa ne-in-nozzle orifice cavitation.

Ngeshwa, alukho ulwazi olwengeziwe mayelana nomklamo, olufana nobukhulu noma indlela yokuvala, olunikeziwe. Omunye umzamo okufanele kukhulunywe ngawo ucwaningo lwakamuva olwenziwe nguButcher et al[6]. Iqembu lakha umbhobho we-quartz ukuze lifunde izifutho ezibilayo ezibilayo ezihambisana nezinjini ezivutha inhlansi futhi lafaka nenaliti eguquliwe ukuze kuncishiswe ukugxiliswa kwengcindezi ku-nozzle kusukela kumandla okuhlala yenaliti. Ingcindezi yomjovo wabo yayinqunyelwe kumabha angama-40.

Ucwaningo lwakamuva kakhulu oluzuze ukucindezelwa komjovo okuphezulu yilolo lukaMitroglou et al[7]. Ababhali bahlole izakhiwo ze-cavitation ngaphakathi kwejometri ye-VCO ekhanyayo enezimbobo eziyisithupha ze-orifice. Bafinyelele amabha angu-400, kodwa ngenxa yokukhula kancane kwamaphutha kanye nesifiso sokuqoqa idatha eyanele ukuze kwakhiwe izithombe ezihlanganisiwe ezilinganiselwe zezakhiwo ze-cavitation, ingcindezi yomjovo yayilinganiselwe kumabha angu-300. I-Cavitation yabonwa ezinhlangothini zombili ze-orifice, njengasocwaningweni lwangaphambili lwe-Arcoumanis. Kulolu cwaningo, i-string cavitation yabonwa kuphela ngesikhathi sokuvula i-valve yenaliti, futhi ihambisana nendawo ye-vortex exhunywe ebusweni benaliti yomjovo.
