KUSINTHA KWA KUSINTHA KWA LIWIRO KWAKULU MU FUEL IJECTOR NOZZLES (gawo 1)

Atomization yamafuta ndiyofunikira pakuwongolera kuyaka mkati mwa injini ya jakisoni. Kuwongolera kuyaka kumathandizira kuchepetsa kutulutsa komanso kukulitsa luso. Cavitation ndi chimodzi mwa zinthu zomwe zimakhudza kwambiri chikhalidwe cha utsi mu chipinda choyaka moto. Manozzles ojambulira mafuta ndi ang'onoang'ono ndipo amagwira ntchito mothamanga kwambiri, zomwe zimalepheretsa kuphunzira zamkati mwa nozzles. Nthawi ndi masikelo aatali amachepetsanso kafukufuku woyeserera wa nozzle ya jekeseni wamafuta. Simulating cavitation mu jekeseni mafuta kudzakuthandizani kumvetsa chodabwitsa ndi kuthandiza mu zina chitukuko.

Kupanga kayeseleledwe kalikonse ka ma cavitating jekeseni nozzles kumayamba ndi malingaliro ofunikira a zomwe zidzaphatikizidwe ndi zomwe zidzanyalanyazidwe. Mpaka pano, palibe mgwirizano wokhudza ngakhale kuvomerezedwa kuti angoganiza kuti phokoso laling'ono, lothamanga kwambiri limakhala mu matenthedwe kapena osaganizira.

Kusiyanasiyana kwa malingaliro kumabweretsa njira zosiyanasiyana zowonetsera. Ngati wina akuganiza kuti mphunoyo ili m'matenthedwe, ndiye kuti palibe kuchedwa kwakukulu kwa Vi pakukula kwa kuwira kapena kugwa chifukwa cha kutentha. Kutentha kwa kutentha kumathamanga kwambiri ndipo zotsatira zopanda pake zimachepetsa kusintha kwa gawo.

Lingaliro la inertial equilibrium limatanthauza kuti magawo awiriwa ali ndi liwiro losasunthika. Kapenanso, pa sub-grid scale level, munthu angaganizirenso kuthekera kwa thovu laling'ono lomwe kukula kwake kumayankha kusintha kwa kuthamanga. Schmidt et al. [1,2] adapanga mitundu iwiri yotsatizana yofananira yomwe idapangidwa kuti ifanizire katulutsidwe kakang'ono, kothamanga kwambiri. HEM imagwiritsa ntchito kulingalira kwa kutentha kwapakati kuti iyese cavitation. Imatengera magawo awiri otaya mkati mwa nozzle mu homogeneous kusakaniza kwa nthunzi ndi madzi.

Ntchitoyi ikuwonetsa kuyerekezera kwa nozzle yothamanga kwambiri, pogwiritsa ntchito HEM ya cavitation, mumitundu yambiri komanso yofananira. Chitsanzocho chikuwonjezedwa kuti chifanizire zotsatira zosagwirizana ndi gawo loyera mumayendedwe ndipo njira yowerengera imasinthidwa kuti ikwaniritse zotsatira zokhazikika mu multidimensional framework.
