Durida Shidaalka Waxqabadka Sare ee EJBR01801Z Naaftada Injector-ka Caadiga ah Qaybaha Injinka Tareenka ee Gawaarida Delphi

Dhuunta irbaddu waa qayb muhiim ah oo sax ah oo isku xidha duritaanka shidaalka iyo astaamaynta, iyo hufnaanta hawleed ee nidaamka duritaanka shidaalka waxaa si weyn u saameeya dabeecadaha socodka gudaha godka. Shidaalka qolka cadaadiska ee gelitaanka tuubada, qaybta isdhaafka ah ee qulqulka qulqulka qulqulka, heerka socodka shidaalka ayaa kordha, cadaadiska maxalliga ah ayaa hoos u dhigaya cadaadiska uumiga saturation ee shidaalka, taasoo keentay cavitation. Burburka xumbo cavitation joogto ah oo hoos yimaada xaaladaha cadaadiska sare, burburka micro-jet-ka iyo cadaadiska saameynta ay keento saameynta gudaha gudaha ee daloolka buufinta, iyada oo la marayo wakhtiga, dusha gudaha ee godka buufinta ayaa soo saari doona dildilaacyada iyo jeexjeexyada, qulqulka qulqulka gudaha iyo buufinta atomation-ka ayaa saameyn doona, iyo xaaladaha daran, tuubada ayaa fashilmi doonta. Sidaa darteed, waxaa muhiimad weyn leh in la barto horumarinta qulqulka cavitation ee gudaha sanka iyo cavitation xirashada dusha derbiga gudaha ee daloolka buufinta.

Qiyaasaha joomatari ee biibiile ayaa saameyn weyn ku leh qulqulka cavitation iyo xirashada cavitation. Shervani et al. iyo Lee et al. ayaa lagu soo gabagabeeyay falanqaynta jilitaanka in kororka taper-ka sanbabada ay si wax ku ool ah u yareeyn karto saameynta burburka xumbo ee xirashada godka dushiisa gudaha ee sanka, iyo in isku halaynta santuuqa la hagaajin doono. Lee iyo al. ka University Hanyang sameeyey daraasad tijaabo ah oo lagu ogaaday in saamiga weyn ee dhererka biibiile in dhexroor, tamar badan ayaa loo baahan yahay si ay u abuuraan cavitation, ie, cavitation waa la xakameeyey sida dhererka biibiile kordhiyaa.Brusiania et al. marka la barbar dhigo waxqabadka hydrodynamic ee nozzles cylindrical iyo conical waxaana la ogaaday in heerka qulqulka gudaha ee qulqulka qulqulka ah uu si weyn hoos ugu dhacay, iyo isku-duubnaanta guud ee socodka ayaa si weyn u wanaajiyay. Marka la eego saadaasha khatarta cavitation, Dular et al. soo gabagabeeyay ka ay falanqaynta in xumbo cavitation ee derbiga u dhow dumin doonaa asymmetrically, iyo soo saaro socodka saamaynta micro-jet in derbiga dhinaca ka fog derbiga gudaha ee nozzle ah.Zhang et al. soosaaray model saadaasha xidhashada cavitation cusub oo ku salaysan aragtida heerka kala iibsiga mass u dhexeeya wejiyada kala duwan iyadoo la baranayo heerka kala iibsiga mass u dhexeeya wejiyada kala duwan oo la xaqiijiyay in biibiile fududeeyey, laakiin model ma si sax ah u saadaaliyo khatarta cavitation, oo ma aha. suurtagal ah in la saadaaliyo khatarta cavitation. Si kastaba ha ahaatee, moodelku ma awoodo inuu bixiyo tilmaame tiro sax ah oo khatarta daloolista ah. Waqtigan xaadirka ah, marka la qiimeynayo khatarta xirashada cavitation ee sanbabada, diiradda ugu weyn waxay tahay aagga sanbabada halkaasoo ay u badan tahay in cavitation ay ka dhacdo iyo qiimeynta heerka xirashada cavitation ee meelo kala duwan oo ku dhex jira sanka. Si kastaba ha ahaatee, ma jiraan wax matalaad tiro ah oo ka mid ah heerka xidhashada meelaha ay u badan tahay in ay ka dhacdo cavitation, waxaana jira la'aan cilmi-baaris ah oo ku saabsan saameynta jaangooyooyinka joomatari ee sanka ee khatarta dhaawaca cavitation.
