2. Vapor recovery - Wikipedia

   en.wikipedia.org/wiki/Vapor_recovery

   In 1975 the Vapor Recovery Gasoline Nozzle was an improvement on the idea of the original gasoline nozzle delivery system. The improved idea was the brain child of Mark Maine of San Diego, California, where Mark was a gas station attendant at a corporate owned and operated Chevron U.S.A. service station.

3. 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 ...

4. Rocket engine nozzle - Wikipedia

   en.wikipedia.org/wiki/Rocket_engine_nozzle

   The gas flow rate is constant (i.e., steady) during the period of the propellant burn. The gas flow is non-turbulent and axisymmetric from gas inlet to exhaust gas exit (i.e., along the nozzle's axis of symmetry). The flow is compressible as the fluid is a gas. As the combustion gas enters the rocket nozzle, it is traveling at subsonic velocities.

5. Nozzle - Wikipedia

   en.wikipedia.org/wiki/Nozzle

   A gas jet, fluid jet, or hydro jet is a nozzle intended to eject gas or fluid in a coherent stream into a surrounding medium. Gas jets are commonly found in gas stoves , ovens , or barbecues . Gas jets were commonly used for light before the development of electric light .

6. Expansion deflection nozzle - Wikipedia

   en.wikipedia.org/wiki/Expansion_deflection_nozzle

   While research into this nozzle continues, it could be used before all its advantages are developed. As an upper stage, where it would be used in a low ambient pressure/vacuum environment specifically in closed wake mode, an E-D nozzle would offer weight reductions, length reductions and a potential increase to the specific impulse over bell nozzles (depending on engine cycle) allowing ...

7. Isentropic nozzle flow - Wikipedia

   en.wikipedia.org/wiki/Isentropic_Nozzle_Flow

   is the density of the gas (kg/m 3) is the temperature of the gas (K) is the cross sectional area of the nozzle at the point of interest (m 2) is the cross sectional area of the nozzle at the sonic point, or the point where gas velocity is Mach 1 (m 2). Ideally this will occur at the nozzle throat.

8. Cyclonic spray scrubber - Wikipedia

   en.wikipedia.org/wiki/Cyclonic_spray_scrubber

   Nozzles have a tendency to plug from particulates that are in the recycled liquid and/or particulates that are in the gas stream. The best solution is to install the nozzles so that they are easily accessible for cleaning or removal. Due to high gas velocities, erosion of the side walls of the cyclone can also be a problem.

9. 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 .
