Hi there. I'm trying to do a diesel combustion simulation with fluent, using a 60° sector geometry (corresponding to one nozzle). I'm facing a few issues i'd like you to enlighen me on please
1-Injection. In the experience i'm modeling, the data provided for injection is :nozzle diameter and spray angle and injection pressure. What is the kng of injection suited for this case (i enable DPM and use by default a solid-cone injection, I define the origin and the axis of the spray , is it OK?) and how can i use the pressure injection for one nozzle hole ?
2- Combustion model. There are a few combustion models in fluent, I'm confused wheter to use the species transport or the non-premixed combustion ? Which one can I use ?

Any info is welcomed !Thanks.
