* For MVD < 200 [micro]m: pneumatic atomizer nozzles
On the one hand, the water supplied to the pneumatic atomizer nozzle must be preheated because smaller droplets tend to freeze before reaching the test section.
It was produced using the same pneumatic atomizer spray nozzles as used for EASA CS-25 [1, Appendix C].

Few authors have tried to measure and model paint sprays originated from pneumatic atomizers so far.
Pneumatic atomizers expose the liquid to a stream of air (lowing at high velocity.
The second method uses
pneumatic atomizers with high atomization pressure ratio to freeze out the droplets produced.
