I would think that the opposite would be true. Liquid particles that are forced to share the same place normally congile into larger particles ... they "pool" together. Like TH said, it would depend mostly on the velocity of the air in which the particles are being injected. This was my theory and why I made my injector valley as deep and spread out as I could. Mine started out deep and shallow and then bleeds out and expands as it meets the floor of the chamber behind the valve.
