Nnukwu Eddy Simulation nke injector diesel na-emepe nwere ụdị cavitation akụkụ abụọ(akụkụ 1)
Abstract.
N'akwụkwọ dị ugbu a, a na-egosipụta nsonaazụ ngosi nke simulation na-asọpụta n'oge mmeghe nke injector Diesel. Iji weghara ogige ịgba ọsọ dị mgbagwoju anya na ihe owuwu cavitation na-etolite na injector, a na-arụ ọrụ Large Eddy Simulation, ebe etinyere mkpakọ nke mmiri mmiri. Maka n'iburu n'uche mmetụta cavitation, a na-arụ ọrụ ụdị ngwakọta otu akụkụ abụọ.
A na-emezi ọnụego mbufe oke nke ụdị ngwakọta iji gbochie oke ihe omume nke nrụgide na-adịghị mma. N'oge ịme anwansị ahụ, achọpụtala ọnụ ọgụgụ nrụgide n'akụkụ uzuoku dara, na oke karịrị 4000bar, nke dị elu nke na-ebute nrụgide nke ihe ndị a na-ahụkarị. Ebe ndị dị otú ahụ nrịgo elu dị elu dabara nke ọma n'ezie ọnọdụ mbuze dị ka achọpụtara site na nyocha X ray.
1. Okwu mmalite
Sistemụ injection mmanụ dizel na-arụ ọrụ dị mkpa n'ime injin mgba ọkụ dị n'ime ebe ọ bụ na ha na-emetụta nguzobe mmanụ ọkụ, atomization na combustion, ihe ndị a kpụrụ akpụ na arụmọrụ injin. Ọsọ ụgbọ elu e hiwere bụ usoro nke 500m / s, yana nrụgide elu dị gburugburu 2000bar. Ihe na-eme ugbu a na-egosi nrụgide injection na ọbụna ịrị elu na 3000bar, iji zute iwu EU n'ọdịnihu na nsị. Agbanyeghị, ọkwa nrụgide dị elu na-ebute oke ọsọ ọsọ site na akụkụ siri ike na injector Diesel na ngwa ngwa siri ike na mgbanwe ntụgharị ihu (nkuku, fillet wdg), nke na-eduga n'ịrụ nrụgide mpaghara na-agbada n'okpuru nrụgide saturation na-akpata cavitation.
Ọzọkwa, cavitation nwere ike iduga mmebi mmebi nke cavitation na mmebi dị njọ nke ọrụ injector, ọbụnadị ọdịda injector dị egwu, nke nwere ike imebi engine, ma ọ bụrụ na ọnụ ọnụ injector kwụsịrị. Enweela ọtụtụ mbọ maka amụma nke ikuku injector diesel, lee eg ọrụ nke Koukouvinis et al. [1].
