If you do not know the conditions you cannot apply a sensible bonudary there. Getting spray velocity and particle size...

The definition of a boundary condition is a location where you know enough about the condition of the flow that you can define it. So for a spray atomisation simulation you have to know the particle...

If you do not know what the injection shape and velocities are you are not going to get very far in your simulation, are you? If you guess the boundary conditions then the simulation output is just...

If the built in models are not suitable then define a new size and velocity distribution to match your atomiser.
