Ihe ọmụma gbasara injector dizel
Cavitation n'ime nnukwu nrụgide ngwa anya na-apụta ìhè mmanụ injector nozzles(NKE 2)
A na-eji nozzles injector nwere ike ịnweta (OA) n'ọtụtụ ọmụmụ gara aga banyere mgbaba ime nke injector nozzle geometries achọtara na igwe mkpakọ na-agbanye ozugbo.Emere ọtụtụ n'ime ọmụmụ ihe ndị a gara aga na nrụgide injection dị ala karịa nke injector ụlọ ọrụ metụtara ya, n'ihi ihe ịma aka nke imepụta injector OA nke nwere ike iguzogide nrụgide injection dị elu.Iji kwụọ ụgwọ, ụfọdụ ejiri geometry agbatịgoro dabara na nọmba Reynolds.
A ga-achikota ọmụmụ nke nwara iru nrụgide injection dị adị n'ebe a, ebe ọ bụ na ndị a bụ ihe kachasị mkpa na nhazi nke ewepụtara n'akwụkwọ a, na n'ikpeazụ bụ nke kachasị mma ma a bịa n'ịmepụta mmụba nke mmasị.
Arcoumanis et al.nyochara mmetụta nke geometry scaling ka ọ na-adakọ ọnụ ọgụgụ Reynolds na Cavitation n'ezigbo ma gbalitekwaa geometry[2].Ha chọpụtara na ihe owuwu cavitation dị iche na geometric abụọ na ọnụọgụ cavitation yiri ya.Ihe ọ̀tụ̀tụ̀ geometry abụọ ahụ gosiri cavitation geometric n'akụkụ mgbada nke elu elu orifice (ya na injector na-atụ aka ala), na cavitation eriri dị n'akụkụ nke ọzọ nke oghere orifice ahụ.
Isi ihe dị iche nke ndị edemede hụrụ bụ ihe dị iche na oge obibi afụ na-asọpụta n'ihi ogologo orifice dị iche iche.Ihe injector buru ibu bụ nke enyo acrylic, ebe ezigbo ọnụ ọgụgụ injector bụ mkpanaka quartz nke etinyere na Bosch common-rail injector body na gbara ya gburugburu ebe ngosi ihe ngosi nkwado acrylic.Iberibe acrylic ahụ buru ibu nke ukwuu karịa imi nchara mbụ nke injector nwetara.Reid et al.jiri sapphire mepụta ụdị geometry dị mfe nke achọtara na injector valve-covered-orifice (VCO)[3].Ha nwetara nrụgide injection nke 2000 mmanya na imewe.Ọ dị ka a rụrụ orifice ahụ site n'itinye efere sapphire n'akụkụ axial nke nwere ọtụtụ oghere site na oghere ndị mebere geometry ikpeazụ.Nke a bụ ụzọ amamihe iji mee ka nhazi akụkụ ahụ dị mfe.
