O lo tatou manuia
Cavitation malosi i totonu o se tui tiso maualuga - o se suʻesuʻega ma suʻesuʻega CFD (vaega 4)
I se aotelega:
O le fa'ata'ita'iga maualuga o le cavitation i totonu o se pu fa'atonutonu na fa'aalia ai se fa'aa'oa'iga fa'ato'aga e le'i va'aia i su'esu'ega muamua. Na faia ni fa'a'ala'au gaogao tetele i luga o le puipui o le orifice ma o le taimi lava na o'o ai le vaega fa'amau, na toe fa'atumuina i luga le alavai i luga o le alavai. Ina ua taunuu le backfilling i le orifice faitotoa, sa i ai se suiga o le fausaga o tafega, toe fuataʻiina le cavitation gaogao tele ma toe fai le faagasologa.
O fa'ata'ita'iga fa'atupu vevesi i le CFD fa'ata'ita'iga na maua mai ai fa'ai'uga e sili atu ona sa'o nai lo fa'ata'ita'iga masani pe a fa'atusatusa i fa'ata'ita'iga.
O le CFD na fetaui ma le pulsing tele void cavitation i luga o le orifice ma le mea na tupu i tua.
O le fa'atele o lenei amio i fa'ai'uga o le CFD na ioeina fo'i ma le fa'ata'ita'iga.
O le CFD na faʻaalia ai o le tafe o le tafe o loʻo faʻafefe foi, e fesoʻotaʻi ma le cavitation amioga o loʻo faʻamatalaina i luga. O le mea moni e faapea o le averesi o le Cd i le CFD na malilie faatasi ma le fuaina i le suʻega na maua ai le mautinoa o le CFD flow rate pulsation e saʻo.
O le fa'aogaina o LSM na mafai ai ona fa'atupuina fa'ata'ita'iga LES CFD i se taimi fa'atonutonu. E tele se taimi na fa'asaoina i le atina'eina o fa'ata'ita'iga mo vaega fa'apitoa.
I le tulaga o le injector moni, o le taimi o le pulsing cavitation sa maualuga tele e faʻaosofia ai le faʻatinoga o le afi. O le fa'ailoaina o le fa'alavelave o lo'o tu'uina mai e lenei galuega o le a mafai ai ona 'alofia so'o se a'afiaga e ono tula'i mai i tulaga fa'ata'atia i le lumana'i.
