2. Propelling nozzle - Wikipedia

   en.wikipedia.org/wiki/Propelling_nozzle

   C-D nozzles can accelerate the jet to supersonic velocities within the divergent section, whereas a convergent nozzle cannot accelerate the jet beyond sonic speed. [ 1 ] Propelling nozzles may have a fixed geometry, or they may have variable geometry to give different exit areas to control the operation of the engine when equipped with an ...

3. Spray nozzle - Wikipedia

   en.wikipedia.org/wiki/Spray_nozzle

   A spray nozzle or atomizer is a device that facilitates the dispersion of a liquid by the formation of a spray. The production of a spray requires the fragmentation of liquid structures, such as liquid sheets or ligaments, into droplets, often by using kinetic energy to overcome the cost of creating additional surface area.

4. Altitude compensating nozzle - Wikipedia

   en.wikipedia.org/wiki/Altitude_compensating_nozzle

   Altitude compensating nozzles address this loss of efficiency by changing the shape or volume of the rocket nozzle as the rocket climbs through the atmosphere. There are a wide variety of designs that achieve this goal, with the aerospike being perhaps the most studied among them. Aerospike engine; Plug nozzle; Expanding nozzle

5. Spray (liquid drop) - Wikipedia

   en.wikipedia.org/wiki/Spray_(liquid_drop)

   Spray nozzle manufacturers all tabulate capacity based on water. Since the specific gravity of a liquid affects its flow rate, the values must be adjusted using the equation below, where Qw is the water capacity and Spg is the specific gravity of the fluid used resulting the volumetric flow rate of the fluid used Qf.

6. Ultrasonic nozzle - Wikipedia

   en.wikipedia.org/wiki/Ultrasonic_Nozzle

   Ultrasonic spray nozzle technology has been used to create films of indium tin oxide (ITO) in the formation of transparent conductive films (TCF). [9] ITO has excellent transparency and low sheet resistance, however it is a scarce material and prone to cracking, which does not make it a good candidate for the new flexible TCFs.

7. Nozzle - Wikipedia

   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". Most commonly found on foam extinguishers and foam handlines. Swirl nozzles inject the liquid in tangentially, and it spirals into the center and then exits through the central hole ...
