Hello
I'm trying to simulate diesel atomization process in Common Rail using Fluent. I already made some resaults but it's not what i wanted. Here are some screens with my resaults. FFF-Setup-Output.jpg FFF-Setup-Output2.jpg FFF-Setup-Output3.jpg predkosc_przekroj.jpg I think i'm making some mistake because single stream it's not looking like injection cone, for example: cone.jpg Can you point me out where i could make mistake? Models used: - Energy - on - Viscous Standard k-e, Standard Wall Function - Species transport - diesel-air - Discrete Phase: - Interaction with continuous phase - Stochastic Collision +, Coalescence +, Breakup+ - Injection model (Cone, 6 streams), droplet, diesel liquid - Velocity 500 m/s - Diameter 0,0016mm - Temerature 350K - start 0- stop 360 angle - Cone angle 60, radous 5mm, Flow rate 0,0079kg/s Time step; 0,0000001s I will give more information about it but at this point this is everything what comes to my head. Thank you for you response. Best Regards! |
