Kev paub txog diesel injector
Cavitation Sab hauv High-Pressure Optically Transparent Roj Injector Nozzles(PIB 2)
Optically nkag tau (OA) injector nozzles tau siv nyob rau hauv ob peb yav dhau los kev tshawb fawb ntawm sab hauv ntws ntawm injector nozzle geometries pom nyob rau hauv ncaj-injection compression-ignition engines.Ntau yam ntawm cov kev tshawb fawb yav dhau los no tau ua tiav ntawm kev txhaj tshuaj siab qis dua li ntawm cov tshuaj muaj feem cuam tshuam nrog kev txhaj tshuaj, vim muaj kev sib tw ntawm kev tsim OA injector uas tuaj yeem tiv taus kev txhaj tshuaj siab.Txhawm rau them nyiaj, qee qhov siv geometries scaled-up kom phim Reynolds tus lej.
Cov kev tshawb fawb uas tau sim kom ncav cuag qhov kev txhaj tshuaj tiag tiag yuav raug sau tseg ntawm no, vim tias cov no yog qhov cuam tshuam tshaj plaws rau cov qauv tsim nyob rau hauv daim ntawv no, thiab thaum kawg yog qhov tseeb tshaj plaws thaum nws los txog rau kev tsim tawm ntawm kev txaus siab.
Arcoumanis et al.tshuaj xyuas cov txiaj ntsig ntawm scaling geometry thaum sib piv Reynolds thiab Cavitation cov lej hauv qhov loj-loj thiab ntsuas geometry[2].Lawv pom tias cov qauv cavitation sib txawv hauv ob lub geometry ntawm cov lej cavitation zoo sib xws.Ob qhov geometry nplai pom geometric cavitation nyob rau sab qaum teb ntawm sab sauv sab saud (nrog rau lub injector taw tes rau hauv qab), thiab hlua cavitation uas muaj nyob rau sab nraud ntawm lub qhov ncauj.
Qhov sib txawv tseem ceeb tau pom los ntawm cov kws sau ntawv tau raug ntaus nqi rau qhov sib txawv ntawm lub sijhawm nyob hauv npuas dej hauv qhov ntws vim qhov sib txawv ntawm qhov ntev.Qhov loj nplai injector yog ua los ntawm acrylic iav, thaum lub sij hawm tiag scale injector yog ua los ntawm ib tug quartz pas nrig txuas mus rau lub Bosch common-rail injector lub cev thiab ib puag ncig los ntawm ib tug acrylic txhawb gallery.Cov khoom acrylic tau loj dua li cov tshuaj txhaj tshuaj thawj cov hlau nozzle.Reid et al.siv sapphire los tsim ib qho yooj yim version ntawm lub geometry pom nyob rau hauv valve-pob-orifice (VCO) injectors[3].Lawv ua tiav kev txhaj tshuaj ntawm 2000 bar nrog tus tsim.Nws zoo nkaus li tias lub orifice tau tsim los ntawm txheej txheej sapphire daim hlau nyob rau hauv axial kev taw qhia nrog ib tug series ntawm thru qhov uas tsim cov geometry zaum kawg.Qhov no yog ib txoj hauv kev ntse kom yooj yim rau kev ua cov khoom.
