Ive been working out the details and Ive tested the both the combustion model seperatly (gas phase) and combined. The simulation works, however the collision seems to not be working very well. The intial breakup of the spray is not captured effectively by the DPM solver.

Here is what i am getting:

 

Where as I should be getting something that looks closer to this.

 

 

Do you know why these collisions are not accurate? I have attached my casefile here for the DPM injections only (40k coarse mesh).
