Diesel engine fuel injector structure and working principle
Cavitation malosi i totonu o se tui tiso maualuga - o se suʻesuʻega ma suʻesuʻega CFD (vaega 1)
Pu'upu'u.
O se tuufaatasiga o faʻataʻitaʻiga ma faʻataʻitaʻiga faʻapitoa faʻataʻitaʻiga ua faʻaaogaina e suʻesuʻe ai le tafega ma le cavitation phenomena o se masini faʻatonutonu i totonu o se tui diesel faʻatinoina maualuga. Na pu'eina le amio fa'aola fa'amalosi i luga o se fa'ata'ita'iga manino lapo'a, lea na fa'aaogaina e atia'e ma fa'amaonia ai se fa'ata'ita'iga CFD fa'atupu vevesi ma le Large Eddy Simulation. O nei metotia o loʻo faʻaaogaina i totonu o Delphi e maua ai le faʻamalamalamaga ma faʻamalieina le faʻatinoina o le injector i le tele-tele.

O le tui tiso e le taumateina o le elemene aupito sili lea ona taua i le ausiaina o le faʻatinoina o afi afi ma le maualalo o faʻamu. O le mea lea e mulimuli mai ai e tatau ona pulea ma le saʻo lelei mea faʻapipiʻi mo afi maualuga. O le iʻuga, e tatau ona faʻatulagaina ma faʻapipiʻiina i luga o le saʻo maualuga le faʻatonuina o le hydraulic valve ma orifices, ma o le malamalama ia latou amio faʻavae o le a maua ai se sao taua i le faʻaogaina ma le faʻaleleia lelei o le faagasologa. E fa'aogaina e Delphi se tu'ufa'atasiga o fa'ata'ita'iga ma fa'ata'ita'iga fa'apitoa fa'apitoa e su'esu'e ai uiga tafe o nei masini.
E pei o mea fou uma, o le High Performance Diesel Injector i lalo o le atinaʻeina i Delphi ua avea ma autu o le tele o gaioiga faʻataʻitaʻiga. E fa'apitoa i lenei pepa, o su'esu'ega a le CFD o galuega fa'atonutonu fa'a hydraulic.
Flow cavitation o se autu masani i masini tui tiso; faʻataʻitaʻiga faʻataʻitaʻiga muamua na faʻaalia ai e le mafai e le faʻataʻitaʻiga o Reynolds-Averaged Navier-Stokes (RANS) faʻataʻitaʻiga faʻataʻitaʻiga ona tuʻuina atu iʻuga saʻo mo amioga faʻamalosi. O le mea lea i le faʻaopoopoga i le galuega CFD, o faʻataʻitaʻiga tetele (LSM) o vaega eseese o galuega faʻatonutonu hydraulic na faʻatonuina. O le faʻaogaina o faʻataʻitaʻiga manino o vaʻa faʻatonutonu ma orifices i fua faʻateleina e mafai ai ona faʻalauteleina le malamalama o le faʻaogaina o le hydraulic [1] e le faigofie ona ausia i isi auala. O le faʻatinoga o le hydraulic e lava le tutoʻatasi i luga o fua uma e aoga e avea o se meafaigaluega faʻaleleia [2].
