ʻO ka mea hoʻoheheʻe Diesel Fuel Injector 095000-8730 Denso Injector no Shangchai, Toyota, Hyundai, Mitsubishi Fuso

Ke hoʻohālikelike ʻia me ka noiʻi hoʻokolohua, ʻoi aku ka nui o ka simulation helu, no laila, ʻo ke ʻano hana helu helu he ala kūpono ia e aʻo ai i ka kahe o ka cavitation i ka injector o ka mīkini diesel kiʻekiʻe, a hiki ke hāʻawi i ka ʻike noiʻi waiwai. I kēia manawa, ua hana nā ʻepekema i kekahi mau noiʻi e pili ana i ka hana ʻana a me ka hoʻomohala ʻana o ka cavitation i loko o ka injector diesel ma o ka hoʻohana ʻana i ke ʻano simulation helu, e ʻimi ana i nā kumu hoʻohālikelike cavitation ʻokoʻa, geometry nozzle, nā kūlana hana a me nā mea ʻē aʻe, a ua holomua ka noiʻi nui. Hiki ke ʻike ʻia mai kēia mau hiʻohiʻona e hoʻohana ʻia ka ʻili o ka paia maʻemaʻe no ka mālama ʻana i ka ʻili o ka paia. ʻO ka ʻoiaʻiʻo, ʻo ka paia o loko o ka nozzle he pā ʻōpala. Ma muli o ke kiʻekiʻe kiʻekiʻe a me nā hiʻohiʻona kiʻekiʻe o ka wai i loko o ka injector, e ʻoi aku ka nui o ke koʻikoʻi shear kokoke i ka paia ʻōpala, kahi e hoʻoulu hou ai i ka wikiwiki a me ke kaomi. Eia naʻe, ʻaʻole maopopo ke ʻano o ka mana o kēia haunaele i nā ʻano kahe o ka cavitation i ka injector. Ma ka hoʻokumu ʻana i kahi kumu hoʻohālike makemakika kūpono e hoʻohālikelike ai i ka kahe o ka cavitation i loko o ka injector diesel, hoʻohana ʻia nā ʻāpana ʻole e like me ka cavitation parameter K a me ka coefficient kahe Cd e wehewehe i nā hiʻohiʻona kahe o ka cavitation i loko o ka nozzle, a me ka mana o ka ʻino o ka pā i ke kahe nui. Aʻo ʻia ka puʻunaue kinoea a me ka hāʻawi wikiwiki ʻana i loko o ka nozzle.

1) Ke emi ke kaomi inlet, emi ke kahe kahe me ka piʻi ʻana o ka ʻino; Ke nui ke kaomi inlet, liʻiliʻi ka mana o ka roughness i ka coefficient kahe.

2) Piʻi mālie ke kahe kahe me ka piʻi ʻana o ka ʻāpana cavitation. Ke ʻoi aku ka nui o ka pākuʻi cavitation ma mua o kekahi waiwai, ʻaʻole e loli hou ke kahe kahe me ka ʻāpana cavitation.
