I-Cavitation Ngaphakathi koxinzelelo oluphezulu lweMibhobho yesitofu seFuel eNgaphandle(ICANDELO 3)

Indlela isixhobo esasitywinwe ngayo, kunye nendlela amacwecwe abanjwe ngayo, ayizange ifakwe kwiziphumo ezipapashiweyo. Iifom ezimbini ze-string cavitation zabonwa: enye eyenziwe kwii-vortices ezifakwe kwindawo yejometri eyenzelwe ukulinganisa inaliti, kunye nenye eyenziwe kwi-vortex edibanisa imingxuma emibini ye-orifice.

Badock et al. ifumene uxinzelelo olunyusiweyo lwenaliti kusetyenziswa imilomo ye-acrylic, nangona ifana ne-Arcoumanis et al, iqhekeza lalilikhulu kakhulu kunombhobho wesitofu sokuqala[4]. Ukufunda ukuqhekeka okuphambili kwesitshizi kwi-nozzle enjalo akunakwenzeka ngenxa yempembelelo ye-lensing yobuso be-drilled reliefs elungisa ubude beepaseji ze-nozzle orifice.

Intsikelelo et al. ifumene uxinzelelo lwenaliti ye-800 bar usebenzisa i-acrylic injector nozzle ene-off-axis orifice enye[5]. Uyilo lwalubumbene ngokwaneleyo ukuvumela ukuqhekeka okuphambili kwe-spray ephumayo kwi-orifice yomlomo ukuba ifundwe ngaxeshanye kunye ne-in-nozzle orifice cavitation.

Ngelishwa, akukho lwazi lulolunye malunga noyilo, olufana nemilinganiselo okanye indlela yokutywina, olunikezelweyo. Omnye umzamo ofanele ukukhankanywa luphononongo lwakutsha nje olwenziwe nguButcher et al[6]. Iqela lenze umbhobho wequartz ukuze lifunde izitshizi ezibilayo ezifunyazayo ezihambelana neenjini zokutshisa iintlantsi kwaye lafakela nenaliti elungisiweyo ukunciphisa uxinzelelo loxinzelelo kumlomo osuka kunyanzeliso lwenaliti yokuhlala. Uxinzelelo lwabo lokutofa lwalulinganiselwe kwi-40 bar.

Olona phononongo lwakutsha nje olufumene uxinzelelo lwenaliti olunyusiweyo lolo lweMitroglou et al[7]. Ababhali bahlolisise izakhiwo ze-cavitation ngaphakathi kwejometri ye-VCO ebonakalayo ebonakalayo enemingxuma emithandathu ye-orifice. Baye bafikelela kwi-400 bar, kodwa ngenxa yokukhula okucothayo kunye nomnqweno wokuqokelela idatha eyaneleyo yokwakha i-avareji yemifanekiso yezakhiwo ze-cavitation, uxinzelelo lwenaliti lwalulinganiselwe kwi-300 bar. I-Cavitation yabonwa kumacala omabini e-orifice, njengoko kuphononongo lwangaphambili lwe-Arcoumanis. Kule sifundo, i-string cavitation yabonwa kuphela ngexesha lokuvula i-valve yenaliti, kwaye ihambelana nendawo ye-vortex efakwe kwi-injector face.
