1 Mafuta anoyerera mukati meinjini yedhiziri

Kuyerera kwedhiziri nozzles inzira yakaoma kwazvo. Kuti udzidze kuyerera mukati menozzle zviri nyore uye zvinobudirira, komputa nhamba yekuenzanisa yave kuitwa.

1.1 Mamiriro ekuvandudza

Parizvino, danho rekusimudzira reinjini dzedhiziri rakanyanya kukwira mafuta ekuyerera mwero, yakakwira jekiseni kudzvinyirirwa uye yakaderera emission.

Pakati pavo, pakugadziriswa kwegomba remuromo, kunaka kwayo kunobatawo zvakananga maitiro eatomization ejini yedhiziri mumunda wekupfapfaidza [!I]. Panguva imwecheteyo, setekinoroji yakakosha inorambidza kuvandudzwa kweinjini dzedhiziri, iyo yakanaka yegomba rekugadzirisa uye kugadzira tekinoroji yemajekiseni emafuta inokosheswa.

Pakati pavo, kunaka kwekugadzirisa kwegomba rehuputi kune zvakanangana nemaitiro eatomization mumunda wekupfapfaidza

1.2 Yakanyanya kutsvagisa zvirimo mubepa rino

Kuti uwedzere kuongorora pesvedzero yekuchinja kweiyo nozzle dhizaini maparamendi pane yekuyerera hunhu muinjini yedhiziri, simulation yenhamba inogona kuitwa kuburikidza neCFD, uye iyi nzira yekuverenga inogona kushandiswa kudzidza iyo nozzle paramita uye shanduko ye mafuta anoyerera mukati memhino, uye uwane mhedzisiro inonzwisisika, kuitira kuti uvandudze mafuta ekupisa.

Mhedzisiro yacho inoratidza kuti sezvo kudzvanywa kwejekiseni kunowedzera, avhareji velocity uye kudzvanywa kwemafuta painobuda nozzle zvishoma nezvishoma inowedzera, uye mutsauko wekumanikidza mugomba remuromo unowedzerawo. Kana iyo mafuta ichiiswa mumunda weatomization, saizi yemadonhwe emafuta inova diki, Iyo yekupinda kureba inova yakareba, iyo mafuta inoyerera velocity inowedzera, uye iyo spray cone angle inova yakakura, pane zvinopesana, iyo yekuisa inoderera.
