UKULINGISWA KWESIVIVINYO ESIPHEZULU OKUFAMBISA IZINOZZLES ZAMAFUTHA (ingxenye 1)

I-atomization kaphethiloli ibalulekile ekulawuleni ukusha ngaphakathi kwenjini yomjovo oqondile. Ukulawula amandla omlilo kusiza ekwehliseni ukungcola kanye nokuthuthukisa ukusebenza kahle. I-Cavitation ingenye yezinto ezithinta kakhulu uhlobo lwesifutho ekamelweni elivuthayo. Imibhobho evamile yokujova uphethiloli mincane futhi isebenza ngengcindezi ephezulu kakhulu, ebeka umkhawulo ekucwaningweni kokuziphatha kombhobho wangaphakathi. Izikali zesikhathi nobude ziqhubeka nokukhawulela ucwaningo lokuhlola lombhobho wokujova uphethiloli. Ukulingisa i-cavitation ku-fuel injector kuzosiza ekuqondeni lesi simo futhi kuzosiza ekuthuthukisweni okuqhubekayo.

Ukwakhiwa kwanoma yikuphi ukulingiswa kwe-cavitating injector nozzles kuqala ngokuqagela okuyisisekelo ukuthi yiziphi izenzakalo ezizofakwa futhi ezinganakwa. 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.

Lokhu kwehluka kwemibono kuholela ezindleleni ezihlukene zokumodela. Uma umuntu ecabanga ukuthi umlomo wombhobho usekulinganisweni kokushisayo, cishe akukho ukubambezeleka okubalulekile kwe-Vi 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 ukuthi kungenzeka yini amabhamuza amancane ubukhulu bawo busabela ezinguqukweni zokucindezela. Schmidt et al. [1,2] ithuthukise imodeli yokulinganisa ye-homogeneous eshintshayo enezinhlangothi ezimbili eyayihloselwe ukulingisa ukugeleza kombhobho omncane, onesivinini esiphezulu. I-HEM isebenzisa ukucabangela kokulingana okushisayo ukuze ilingise i-cavitation. Ithatha ukugeleza kwezigaba ezimbili ngaphakathi kwembobo yengxube ye-homogeneous yomhwamuko noketshezi.

Lo msebenzi wethula ukulingiswa kwenozzle yesivinini esikhulu, kusetshenziswa i-HEM ye-cavitation, kuhlaka olubanzi noluhambisanayo. Imodeli inwetshiwe ukuze ilingise imiphumela engeyona yomugqa yesigaba esimsulwa ekugelezeni futhi indlela yezinombolo iyalungiswa ukuze kuzuzwe umphumela ozinzile kuhlaka lwe-multidimensional.
