That appears to be what is happening just by looking at the graphs but I don’t have stochoastic collision turned on (which is where coalesence would occur) so I don’t think that should be the case.

UPDATE: If I turn off breakup this problem doesn’t seem to occur and the droplet diameters are as predicted. However the velocity profile means the spray doesn't hold its cone shape as only the particles heading in the z direction have high velocity and the rest of the cone is significantly lower, it is like this:


Is there a setting so that the velocity is more evenly distributed in the cone so it holds its shape instead of the central core dominating it like that?
