   Atomizer nozzles are used for spray painting, perfumes, carburetors for internal combustion engines, spray on deodorants, antiperspirants and many other similar uses. Air-aspirating nozzles use an opening in the cone shaped nozzle to inject air into a stream of water based foam (CAFS/AFFF/FFFP) to make the concentrate "foam up".

5. Fog nozzle - Wikipedia

   en.wikipedia.org/wiki/Fog_nozzle

   A fog nozzle. A fog nozzle is a firefighting hose spray nozzle that breaks its stream into small droplets.By doing so, its stream achieves a greater surface area, and thus a greater rate of heat absorption, which, when compared to that of a smoothbore nozzle, speeds its transformation into the steam that smothers the fire by displacing its oxygen.

6. de Laval nozzle - Wikipedia

   en.wikipedia.org/wiki/De_Laval_nozzle

   A de Laval nozzle (or convergent-divergent nozzle, CD nozzle or con-di nozzle) is a tube which is pinched in the middle, with a rapid convergence and gradual divergence. It is used to accelerate a compressible fluid to supersonic speeds in the axial (thrust) direction, by converting the thermal energy of the flow into kinetic energy .

7. Tip jet - Wikipedia
