Cavitation dị egwu n'ime injector diesel na-arụ ọrụ dị elu - nnwale na nyocha CFD (akụkụ 4)
Na nchịkọta:
Onyonyo dị elu nke cavitation n'ime orifice njikwa gosipụtara mmetụta hydraulic na-agbapụta nke a na-ahụbeghị na ọmụmụ gara aga.E kere nnukwu cavitation efu n'akụkụ mgbidi orifice na ozugbo akụkụ conical ruru, nkwụghachi azụ mere n'elu ugwu n'akụkụ orifice ahụ.Mgbe ndochi azụ rutere n'ọnụ ụzọ orifice, enwere mgbanwe nhazi usoro eruba, nnukwu cavitation efu megharịrị na usoro ahụ ugboro ugboro.
Nlegharị anya ọgba aghara dị elu na ịme anwansị CFD rụpụtara nsonaazụ ziri ezi karịa ụdị ọkọlọtọ ma e jiri ya tụnyere nsonaazụ nnwale.
CFD dakọtara na nnukwu cavitation efu na-agbapụta n'akụkụ orifice na mmemme ndochi azụ.
Ugboro omume a na nsonaazụ CFD kwenyekwara na nnwale ahụ.
CFD kpughere na ọnụ ọgụgụ na-erugharị ahụ na-ama jijiji, jikọtara ya na omume cavitation akọwara n'elu.Eziokwu ahụ bụ na nkezi Cd dị na CFD kwenyere na nke a tụrụ na nnwale ahụ mere ka obi sie gị ike na pulsation ọnụego CFD ziri ezi.
Iji LSM mere ka mmepe nke ụdị LES CFD n'ime oge a na-ejikwa ya.Nke a na-azọpụta oge dị ukwuu n'ịmepụta ụdị maka ngwa ngwa n'ezie.
N'ihe banyere ezigbo injector, ugboro nke cavitation pulsing dị oke elu iji metụta ọrụ engine.Mmata nke ihe omume a na-enye site na ọrụ a ga-enyere aka zere mmetụta ọ bụla nwere ike ịdaba na ọkwa nhazi n'ọdịnihu.
