Suau'u Suauu Diesel Injector 456-3493 mo Caterpillar C9.3 CAT Truck Engine Spare Parts

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'amalosi 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 mautinoa lava o le elemene sili ona taua i le ausiaina o le faʻaogaina o le afi faʻapitoa ma le maualalo o faʻaulu.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 fa'aogaina o fa'ata'ita'iga manino o va'a fa'atonutonu ma orifice i fua fa'atuputeleina e mafai ai ona fa'atupuina le malamalama i le fa'atinoina o le hydraulic [1] e le faigofie ona ausia i isi metotia.O le faʻatinoga o le hydraulic e lava le tutoʻatasi i luga o fua uma e aoga e avea o se meafaigaluega faʻaleleia [2].
