That implies the isn't a great deal of turbulent dispersion, so the parcels aren't separating. You can try adapting the inlet region as that'll increase the number of facets and so increase the parcel count. However it also suggests the particles may not be arriving at the unit like that in reality so some more thought into where/how many of particles need to be added into the model: that's a question for the experimentalists.
