Mhedzisiro yedhayamita yenozzle, kudzvanywa kwejekiseni uye ambient tembiricha pane yekupfapfaidza maitiro muinjini yedhiziri (chikamu 1)

1. Nhanganyaya

Mafuta anopinzwa mukamuri akakosha kune injini yedhiziri nekuti inopesvedzera kuita uye kuburitsa.Munguva yekupisa, pfapfaidzo ingori kupinza kwemvura munzvimbo ine gasi kuburikidza nemuromo zvekuti mvura, kuburikidza nekudyidzana kwayo negasi rakatenderedza uye nekusagadzikana kwayo, inotsemuka-inoputika kuita madonhwe [1].Kupfapfaidza maitiro anozivikanwa kukanganisa zvakanyanya kupisa uye emission maitiro mumainjini edhiziri.Nekunatsiridza hunhu hwekupfapfaidza, mhepo yakasvibirira kubva muinjini yedhiziri iyo inonyanya NOx uye PM inogona kudzikiswa [2-4].Kuferefeta mukati medhiziri yekupfapfaidza maitiro akanyanya pamusoro pekuita kwepfapfaidzo hunhu pakuita kweinjini senge kupfapfaidza tip kupinda, kureba-kureba uye saizi yedonhwe uye kukurumidza kugovera [5]. ].Iyo yekupfapfaidza tip yekupinda inotora nguva yakareba sezvo jekiseni rinowedzera.Ichi chigumisiro chine hukama nehupamhi hwepamusoro uye hupamhi hwepamusoro hwemadonhwe pamagetsi ejekiseni akakwirira [7].Yakaenzana nekumanikidzwa kwejekiseni, pfapfaidzo inopinda nekukurumidza kune yakakwirira jekiseni kumanikidza [8].Kureba-kureba kunoratidza nzvimbo yekusaenderera, apo pfapfaidzo inoshanduka kubva munzvimbo yemvura (yakawanda mvura, kana yakabatana ligaments uye madonhwe), kuenda kune yakatsetseka atomized hutongi hwemadonhwe [9].Mushure mekupatsanurwa kwekoramu yemvura inobuda kubva mumhuno, madonhwe anogadzirwa anogona kuwedzera kupatsanuka kuita madiki sezvaanopinda mugasi rakatenderedza [10].Kuvandudzwa kweiyi deformation kunotungamirira kukuparadzana kuita madonhwe maduku.

Masimba anobatanidzwa nekumanikidzwa kwesimba, kushushikana kwepamusoro uye viscosity kunodzora kuparara kwedonhwe [11-12].Nekudaro, CFD chishandiso chekukanganisa chiri kushandiswa kufanotaura chikamu chakakosha chisingagone kuitwa mukuyedza.Mutsvagiridzo iyi, maitiro edhiziri yekupfapfaidza anoferefetwa achitarisa kushandura ambient tembiricha, jekiseni kudzvanywa nedhayamita yenozzle yakasiyana nekushandisa Computational Fluid Dynamics.Iyi simulation inogona kubata Droplet dhayamita, kupfapfaidza kupinda uye kureba kwekuparadzana.
