Loj Eddy Simulation ntawm diesel injector qhib nrog ob theem cavitation qauv(part 1)
Abstract.
Nyob rau hauv daim ntawv tam sim no, qhia cov txiaj ntsig ntawm kev simulation ntws thaum lub sij hawm qhib lub Diesel injector tau nthuav tawm. Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau ua rau cov kab mob ua rau cov kab mob ua rau cov kab mob ua rau cov kab mob ua rau lub cev ua haujlwm tau ua haujlwm tau ua haujlwm, qhov loj Eddy Simulation tau ua haujlwm. Rau kev coj mus rau hauv tus account cavitation teebmeem, ob theem homogenous sib xyaw qauv tau ua haujlwm.
Kev hloov pauv loj ntawm cov qauv sib xyaw tau hloov kho kom txo tau ntau npaum li qhov ua tau ntawm qhov tshwm sim ntawm qhov tsis zoo. Thaum lub sij hawm simulation, lub siab peaks tau pom nyob rau hauv cov cheeb tsam ntawm vapor vapor, nrog rau qhov loj tshaj 4000bar, uas yog siab dua qhov kev ntxhov siab ntawm cov khoom siv. Qhov chaw ntawm qhov siab siab siab sib raug zoo nrog qhov chaw yaig tiag tiag raws li pom los ntawm X-ray scans.
1. Taw qhia
Diesel txhaj tshuab ua lub luag haujlwm tseem ceeb hauv cov tshuab hluav taws xob sab hauv vim lawv cuam tshuam rau kev tsim cov roj txau, atomization thiab combustion, tsim emissions thiab lub cav efficiency. Lub dav hlau velocities tsim yog ntawm qhov kev txiav txim ntawm 500m / s, nrog rau sab sauv siab nyob ib ncig ntawm 2000bar. Cov qauv tam sim no qhia txog kev txhaj tshuaj kom nce mus txog 3000bar, txhawm rau ua kom tau raws li EU txoj cai lij choj yav tom ntej hauv emissions. Txawm li cas los xij, cov qib siab siab ua rau muaj kev nrawm nrawm los ntawm cov kab nruj hauv Diesel injector thiab muaj zog acceleration nyob rau hauv cov kev taw qhia ntse hloov (cov ces kaum, fillets thiab lwm yam), uas ua rau lub zos static siab poob qis hauv qab lub siab saturation thiab ua rau cavitation.
Tsis tas li ntawd, cavitation tuaj yeem ua rau cavitation yaig kev puas tsuaj thiab kev puas tsuaj loj ntawm cov tshuaj txhaj tshuaj, txawm tias muaj kev puas tsuaj rau lub tshuab tsis ua haujlwm, uas tuaj yeem ua rau lub cav puas tsuaj, yog tias lub taub hau tawg. Muaj ntau qhov kev siv zog rau kev twv ua ntej ntawm Diesel injector yaig, saib piv txwv li kev ua haujlwm ntawm Koukouvinis li al. [1].
