Cavitation Mukati Yepamusoro-Kudzvanya Optically Transparent Fuel Injector Nozzles(CHIKAMU 7)

4 Mhedziso (enderera)

Iyi nzira yakafunga nzira dzakajairika dzekutadza zvinhu zve brittle zvinhu, uye yakashandisa Finite Element Analysis kugadzirisa mitoro yekushanda pamuromo zvakadzama. Dhizaini yakashandisa machira esafire ane akareruka geometries kudzvanya acrylic nozzle chidimbu kuitira kudzikisira kushushikana kwemukati mechidimbu uko kudzvanywa kwemafuta kwakaiswa. Kune yakapihwa simba rekumanikidza, dhizaini iyi haina kudhura pane imwe chete yakagadzirwa nesafire uye yakasimba pane imwe chete yakavakwa kubva kuacrylic.

Iyo cavitation muorifices yakaratidza kutsamira pane geometry, kunyanya painorerekera kona yepakati axis ye orifice. Kunyange zvazvo cavitation yakawanikwa kumativi ose e orifice nehombe yekona yekona, yakanga isiri nekuda kwetambo cavitation, iyo iyo cavitation munharaunda iyi yave ichinyanya kufungidzirwa mune zvidzidzo zvekare.

Basa remangwana richabvisa maburi ekubvisa kubva kumasafiya masimbi, uye panzvimbo pacho shandisa zvimedu zvesafire zviri nyore zvakaiswa mukati mesimbi isina tsvina. Shanduko iyi inotarisirwa kudzikisira kushushikana mupfungwa muzvidimbu zvesafire uye kubvumira masimba makuru ekusunga kupfuura zvaigoneka neyakapfuura dhizaini.

Zvidimbu zvitsva zvichayedzwa kuti zvisimbise kuita kwavo uyezve zviedzo zvichaitwa pamusoro pehuwandu hwekumanikidzwa kwemashure (cavitation umbers) mukamuri yakamanikidzwa. Izvi zvinogadzira huwandu hwe cavitating inoyerera yekuwedzera kudzidza.

5 Kutenda

Vanyori vanoda kuonga EU nekutsigira basa iri pasi pechirongwa cheHERCULES-C, uyewo kutenda Swedish Energy Agency nokuda kwekutsigirwa kwavo.
