Dizilo injector orifice flow cavitation ngozi
Mphuno ya jekeseni ndi gawo lofunikira kwambiri lomwe limalumikiza jakisoni wamafuta ndi ma atomisation, ndipo magwiridwe antchito a jekeseni wamafuta amakhudzidwa kwambiri ndi mawonekedwe akuyenda mkati mwa mphuno. Mafuta mu chipinda choponderezedwa mu cholowera cha nozzle, gawo lodutsa gawo la kutsika kwa njira, kuchuluka kwa mafuta kumawonjezeka, kupanikizika kwapafupi kumachepetsedwa mpaka kutsika kwa nthunzi yamafuta, zomwe zimapangitsa cavitation. Mosalekeza kwaiye cavitation kuwira kugwa pansi pa zinthu mkulu-anzanu, kugwa kwa yaying'ono-ndege ndi mavuto ake kuthamanga kwaiye ndi zotsatira za mkati pamwamba pa dzenje kutsitsi, m'kupita kwa nthawi, mkati padziko dzenje kutsitsi adzabala. ming'alu ndi craters, nozzle mkati otaya ndi kutsitsi atomisation adzakhudzidwa, ndipo zikavuta, nozzle adzalephera. Choncho, n'kofunika kwambiri kuphunzira chitukuko cha cavitation otaya mkati nozzle ndi cavitation kuvala pa mkati khoma pamwamba pa dzenje kutsitsi.
Ma geometrical parameters a nozzle amakhala ndi chikoka chachikulu pa cavitation flow and cavitation wear.Shervani et al. ndi Lee et al. anamaliza kudzera kayeseleledwe kusanthula kuti kuwonjezeka taper wa nozzle akhoza bwino kuchepetsa zotsatira za kuwira kugwa pa cavitation kuvala pa mkati padziko nozzle, ndi kuti kudalirika kwa nozzle adzakhala bwino. Lee et al. kuchokera ku yunivesite ya Hanyang anachita kafukufuku woyesera ndipo anapeza kuti kukula kwakukulu kwa chiŵerengero cha nozzle kutalika kwa m'mimba mwake, mphamvu zambiri zimafunika kuti apange cavitation, mwachitsanzo, cavitation imaponderezedwa pamene kutalika kwa nozzle kumawonjezeka.Brusiania et al. Poyerekeza machitidwe a hydrodynamic a cylindrical ndi conical nozzles ndipo adapeza kuti kuchuluka kwa otaya mkati mwa mphuno ya conical kumachepetsedwa kwambiri, ndipo kufananiza konseko kumayendetsedwa bwino. Pankhani ya kuneneratu kwa chiwopsezo cha cavitation, Dular et al. anamaliza kusanthula awo kuti thovu cavitation pafupi khoma adzagwa asymmetrically, ndi kutulutsa yaying'ono-ndege zimakhudza otaya khoma kumbali kutali kwambiri ndi khoma lamkati la nozzle.Zhang neri Al. anatengera latsopano cavitation kuvala kulosera chitsanzo zochokera chiphunzitso cha misa kutengerapo mlingo pakati pa magawo osiyanasiyana pophunzira misa kutengerapo mlingo pakati pa magawo osiyanasiyana ndi kutsimikizira izo mu nozzle chosavuta, koma chitsanzo sanathe molondola kuneneratu chiopsezo cavitation, ndipo si. zotheka kulosera kuopsa kwa cavitation. Komabe, chitsanzo sangathe kupereka molondola kachulukidwe khalidwe la cavitation chiopsezo. Pakalipano, poyesa kuopsa kwa kuvala kwa cavitation mu nozzle, cholinga chachikulu ndicho kudera la nozzle komwe cavitation ikhoza kuchitika ndikuwunika kuchuluka kwa cavitation kuvala m'malo osiyanasiyana mkati mwa nozzle. Komabe, palibe chifaniziro chochuluka cha kuchuluka kwa kuvala m'madera omwe cavitation ingathe kuchitika, ndipo pali kusowa kwa kafukufuku wa zotsatira za magawo a geometric a nozzle pa chiopsezo cha kuwonongeka kwa cavitation.
