Cavitation Mukati Yepamusoro-Kudzvanya Optically Transparent Fuel Injector Nozzles(CHIKAMU 2)

Optically accessible (OA) jekiseni nozzles akashandiswa mune akati wandei apfuura zvidzidzo zvemukati mafambiro einjector nozzle geometries anowanikwa mune yakananga-jekiseni compression-ignition injini. Zvizhinji zvezvidzidzo izvi zvakapfuura zvakaitwa pakumanikidzwa kwejekiseni zvakanyanya kuderera pane izvo zvine chekuita nemajekiseni emaindasitiri, nekuda kwedambudziko rekugadzira jekiseni reOA rinokwanisa kushingirira majekiseni makuru. Kuripa, vamwe vakashandisa yakasimudzwa-up geometries kuenzanisa nhamba yaReynolds.

Zvidzidzo zvakayedza kusvika kumanikidziro ejekiseni echokwadi zvichapfupikiswa pano, sezvo izvi zviri izvo zvakanyanya kuenderana nedhizaini yakapihwa mubepa rino, uye pakupedzisira ndiyo yakanyanya kunaka kana zvasvika pakuburitsa kuyerera kwekufarira.

Arcoumanis et al. yakaongorora mhedzisiro yekuyera geometries ichifananidza nhamba dzeReynolds neCavitation muhukuru-chaiyo uye yakasimudzwa geometry[2]. Vakaona kuti zvimiro zvecavitation zvaive zvakasiyana mumajiometri maviri pane akafanana cavitation manhamba. Masero ese ejometri airatidza geometric cavitation padivi rezasi rekumusoro orifice mupendero (ine jekiseni rakanongedza pasi), uye tambo cavitation iripo kune mhiri kwegomba regomba.

Musiyano mukuru wakaonekwa nevanyori wakakonzerwa nemusiyano wenguva yekugara kwebubble mukuyerera nekuda kwehurefu hwakasiyana. Iyo jekiseni hombe yakagadzirwa negirazi re acrylic, nepo jekiseni rechiyero chairo rakagadzirwa netsvimbo yequartz yakanamirwa kune Bosch common-rail jekiseni muviri uye yakakomberedzwa neiyo acrylic inotsigira gallery. Iyo acrylic chidimbu chaive chakakura zvakanyanya kupfuura chepakutanga simbi yejekiseni. Reid et al. akashandisa safire kugadzira shanduro yakareruka yejometri inowanikwa muvharuvhu-yakavharwa-orifice (VCO) majekiseni[3]. Vakawana kumanikidzwa kwejekiseni ye2000 bar nedhizaini. Zvinoita sekuti iyo orifice yakavakwa nekumisikidza mahwendefa esafire munzira yeaxial ine nhevedzano ye thru maburi ayo akagadzira yekupedzisira geometry. Iyi yaive nzira yakangwara yekurerutsa magadzirirwo ezvikamu.
