Ukuthuthukisa Imodeli Yenqubo Yokujova Kagesi Ukuhlaziya Ukusebenza Komjovo Wezinjini Zedizili(ingxenye 5)

Ngenxa yokuhlakazeka, i-fuel jet iguqulwa ibe isifutho sikaphethiloli esinokusabalalisa kosayizi othile weconsi. Ngaphezu kwalokho, i-diameter yokudonsa iyinani eliqhubekayo elingahleliwe, okusho ukuthi lingathatha noma yiliphi inani ngesikhathi sencazelo yalo. Kulokhu, i-fuel spray akufanele ibhekwe nje kuphela njengeqoqo noma isethi yamaconsi, kodwa njenge-static aggregate yamaconsi obukhulu obuhlukahlukene.

Ngokwemithetho yokusabalalisa ecatshangelwayo, okungenani amapharamitha amabili ayadingeka ukuze utadishe i-spectrum kasayizi wokuhla kaphethiloli owenziwe nge-athomu: isilinganiso sobubanzi bokwehla kanye nezici zokusabalalisa indiza (ukuhlakazeka, ububanzi).

Indlela ye-Sauter mean drop diameter ikhethiwe. Imele isilinganiso sevolumu yawo wonke amaconsi endaweni yawo ephelele.

Ukwenziwa kwe-athomu yesibaseli kuncike enombolweni ye-Weber, okuyinani elingenasici elisungula ubudlelwano phakathi kwamapharamitha amathathu athonya ukucoleka kwe-atomization yoketshezi futhi etholakala kunkulumo.

Isimiso esingenasici sixhumanisa amapharamitha amane athonya ukucoleka kwe-atom kaphethiloli (3)rT - ukuminyana kukaphethiloli kg/m3 phakathi kwendawo ephuma emlonyeni wombhobho kanye nendawo lapho umjovo ojova khona; cd - nozzle orifice ububanzi, m; σ - ukungezwani kwendawo kaphethiloli, N/m, mT – viscosity yamafutha ashukumisayo, Ns/m2

Umthelela obalulekile ekwenziweni kwe-atom kaphethiloli ubangelwa izinga uketshezi olugeleza ngalo luphuma endaweni ephuma emlonyeni wombhobho. Izinga lokugeleza kukaphethiloli lapho ukuhlakazeka kuqala khona ngokushesha emgodini we-nozzle kuncike ezintweni eziningi (4):
