Ukulingisa Ukugeleza Kwesivinini Esikhulu KumaNozzles Wokujova Isibaseli (ingxenye 6)

Usayizi omncane, isivinini esikhulu kanye nesilinganiso sesikhathi esilinganiselwe kwenza kube nzima kakhulu ukufunda ukuziphatha ngokuhlolwa. I-cavitation yokumodela ingaba usizo ekulingiseni ukugeleza kumabhobho omjovo kasayizi wangempela kanye nokufunda izici zenozzle yangaphakathi, ezithinta ukugeleza ngaphakathi kombhobho.

Ukwakhiwa kwanoma yikuphi ukulingiswa kwe-cavitating injector nozzles kuqala ngokuqagela okuyisisekelo kokuthi iyiphi into okufanele ifakwe futhi izonakwa [12]. Kuze kube manje, akukaze kube khona ukuvumelana mayelana nokuthi kuyamukeleka yini ukucabanga ukuthi ama-nozzles amancane, anesivinini esikhulu se-cavitating asekulinganisweni kwe-thermal noma inertial. Uma umuntu ethatha ngokuthi umlomo wombhobho usekulinganisweni kokushisa, cishe akukho ukubambezeleka okubalulekile ekukhuleni kwebhamuza noma ukuwa ngenxa yokudlulisa ukushisa. Ukudlulisa ukushisa kuyashesha kakhulu futhi imiphumela engenzi lutho ikhawulela ukuguquka kwesigaba. Ukucatshangelwa kokulingana kwe-inertial kusho ukuthi lezi zigaba ezimbili zinesivinini sokushelela esinganaki.

Kungenjalo, ezingeni lesikali segridi engaphansi, umuntu angase futhi acabangele amathuba okuba amabhamuza amancane ubukhulu bawo buphendule izinguquko zokucindezela. Lokhu kwehluka kwemibono kuholela ezindleleni ezihlukene zokumodela. Ukulingisa kwe-cavitating atomizer nozzles njalo kudinga ukucabanga okulula. Le mibono kufanele yanele ukwenza inkinga ixazululeke ngaphandle kokukhiqiza amaphutha angamukelekile. Inhloso yalo msebenzi ukwakha isixazululi se-CFD esinezinhlangothi ezintathu ukuze silingise ukugeleza kumbobho ye-cavitating encane, enesivinini esiphezulu kusetshenziswa imodeli yokulingana elinganayo (HEM). I-HEM esetshenziswe kulo msebenzi inweba imodeli echazwe nguSchmidt et al. [1,2] kuhlaka olunezinhlangothi eziningi noluhambisanayo. Imodeli inwetshiwe ukuze ilingise imiphumela engeyona yomugqa yesigaba esihlanzekile ekugelezeni futhi indlela yezinombolo ihluke emsebenzini kaSchmidt et al.
