Atomization of diesel
 

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.

I think i'm making some mistake because single stream it's not looking like injection cone, for example:

Attachment 57607

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!
