I-Common Rail Nozzle DLLA149P2166 ye-Diesel Fuel injector 0445120215 0 445 120 215 ye-Bosch Nozzles

Ukulinganisa ukuHamba okuPhakamileyo kwiMibhobho yesitofu seFuel (icandelo 6)

Ubungakanani obuncinci, isantya esiphezulu kunye nesikali esilinganiselweyo sexesha senza kube nzima kakhulu ukufunda indlela yokuziphatha ngokulinga.Ukulinganisa i-cavitation kunokuba luncedo ekufaniseni ukuhamba kwimibhobho ye-injector yobukhulu bokwenyani kunye nokufunda iimpawu ze-nozzle zangaphakathi, ezichaphazela ukuhamba ngaphakathi kwe-nozzle.

Ukwakhiwa kwanoma yimuphi ukulinganisa kwe-cavitating injector nozzles kuqala ngeengcinga ezisisiseko zeziphi izinto eziza kubandakanywa kwaye ziyakungahoywa [12].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.Ukuba umntu ucinga ukuba umbhobho ukwi-equilibrium ye-thermal, ngoko akukho kulibaziseka okubalulekileyo ekukhuleni kweqamza okanye ukuwa ngenxa yokudluliselwa kobushushu.Ukutshintshwa kobushushu kukhawuleza ngokungenasiphelo kwaye iziphumo ezingenasiphelo zinciphisa utshintsho lwesigaba.Ukucingelwa kolungelelwaniso lwe-inertial kuthetha ukuba izigaba ezibini zinesantya sokutyibilika esingakhathaliyo.

Kungenjalo, kwinqanaba lesikali segridi engaphantsi, umntu unokuphinda athathele ingqalelo ukuba nokwenzeka kwamaqamza amancinci anobukhulu obuphendula utshintsho kuxinzelelo.Le yantlukwano yezimvo ikhokelela kwiindlela ezahlukeneyo zemodeli.Ukulinganisa i-cavitating atomizer nozzles rhoqo kufuna ukwenza lula ucingelo.Ezi ngcinga kufuneka zanele ukwenza ukuba ingxaki ilungiswe ngaphandle kokuvelisa iimpazamo ezingamkelekanga.Injongo yalo msebenzi kukwakha isombululi se-CFD esine-dimensional-dimensional-dimensional CFD ukulinganisa ukuhamba kwi-nozzle encinci, i-high-speed cavitating nozzle usebenzisa i-homogeneous equilibrium model (HEM).I-HEM esetyenziswe kulo msebenzi yandisa imodeli echazwe nguSchmidt et al.[1,2] kwisakhelo esine-multidimensional and parallelised.Imodeli yandisiwe ukuze ifanise imiphumo engeyiyo yomgca yesigaba esicocekileyo ekuhambeni kwaye indlela yamanani ihluke kumsebenzi kaSchmidt et al.
