Oil combustion problem
 

I have a problem about oil combustion:

I want to simulate a oil combustion in a small burning device with oil burner.

I have select:

EDC combustion model (A=4, B=-1)
k-e turbulent model
soot formation model

Reactions: JetA WD2 NO PDF

I have a problem with a injection method. Which is most appropriate for oil burner? cone injection or cone with primary breakup- blob method?

Is a secondary breakup important in my example or not?

I have no measuements for injection velocity- i think it is 37 m_s (9 bar)- is it correct?

Thank in advance for help

How to do simulation of gas combustion
 

Hi, I m doing research on the field of natural gas combustion in pipelines after leakage. please anyone can help in CFX or fluent.
