UMFANO WOKUQHUBEKA OKUPHEZULU OKUPHEZULU KWINOZZLES ZESITOFU ESIFUTSHANE (icandelo 1)

I-atomization yesibaso ibalulekile ekulawuleni ukutsha ngaphakathi kwe-injini yokutofa ngokuthe ngqo. Ukulawula ukutsha kunceda ekunciphiseni izinto ezikhutshwayo kunye nokwandisa ukusebenza kakuhle. I-Cavitation yenye yezinto ezichaphazela kakhulu uhlobo lwe-spray kwigumbi lokutsha. Imilomo yesitofu se-fuel eqhelekileyo mincinci kwaye isebenza kuxinzelelo oluphezulu kakhulu, olunciphisa uphononongo lokuziphatha kombhobho wangaphakathi. Ixesha kunye nezikali zobude zinciphisa ngakumbi uphononongo lokulinga lombhobho wesitofu sesibaso. Ukulinganisa i-cavitation kwi-injector ye-fuel injector kuya kunceda ekuqondeni i-phenomenon kwaye kuya kunceda ekuphuhliseni okuqhubekayo.

Ukwakhiwa kwanoma yimuphi ukulinganisa kwe-cavitating injector nozzles kuqala ngeengcinga ezisisiseko zeziphi izinto eziza kubandakanywa kwaye ziyakungahoywa. Ukuza kuthi ga ngoku, akukho mvumelwano malunga nokuba kwamkelekile ukucinga ukuba i-nozzles encinci, i-high-speed-speed cavitating nozzles i-thermal or inertial equilibrium.

Le yantlukwano yezimvo ikhokelela kwiindlela ezahlukeneyo zokubonisa. Ukuba umntu ucinga ukuba umlomo wombhobho ukwi-equilibrium ye-thermal, ngoko akukho kulibaziseka okubalulekileyo kwe-Vi ekukhuleni kweqamza okanye ukuwa ngenxa yokudluliselwa kobushushu. Ukugqithiswa kobushushu kukhawuleza ngokungenasiphelo kwaye iziphumo ezingenasiphelo ziyanciphisa utshintsho lwesigaba.

Ukucingelwa kolungelelwaniso lwe-inertial kuthetha ukuba izigaba ezibini zinesantya sokutyibilika esingakhathaliyo. Kungenjalo, kwinqanaba le-sub-grid scale, umntu unokuphinda athathele ingqalelo ukuba nokwenzeka kwamaqamza amancinci ubukhulu bawo buphendula utshintsho kuxinzelelo. Schmidt et al. [I-1,2] iphuhlise imodeli elinganayo yokulinganisa i-dimensional transient-transient homogeneous equilibrium eyenzelwe ukulinganisa i-nozzle encinci, ehamba ngesantya esiphezulu. I-HEM isebenzisa ingqikelelo ye-thermal equilibrium ukulinganisa i-cavitation. Ithatha inqanaba lokuhamba kwezigaba ezibini ngaphakathi komlomo kumxube we-homogeneous womphunga kunye nolwelo.

Lo msebenzi ubonisa ukulinganisa kwe-nozzle yesantya esiphezulu, usebenzisa i-HEM ye-cavitation, kwi-multidimensional and parallel framework. Imodeli yandisiwe ukuze ifanise imiphumo engeyiyo yomgca yesigaba esicocekileyo ekuhambeni kwaye indlela yamanani iguqulwa ukuze kuphunyezwe umphumo ozinzileyo kwisakhelo se-multidimensional.
