varunrajendra is on a distinguished road
I have been trying to simulate spray using single orifice atomizer (and pressure swirl atomizer) injector models. Liquid Diesel droplets into ambient air.

I have a doubt regarding use of Species Transport.

When I select a mixture in the species transport does it define the fluid domain as the mixture....??

The Particle Type = Droplet is disabled in the injector definition window. I am using k-epsilon turbulance model and also DPM...

I noticed that Droplet option gets enabled when i enable Species Transport. But i'm unable to understand how to get sort out the issue.

I would appreciate it if any one could tell me how to overcome this, or to use droplet model is it compulsary to use Species Transport?? and if yes how do i retain the domain to be ambient air??
