nozzle

i. A duct, tube, pipe, spout, or the like through which a fluid is directed and discharged from its open end. It is designed to meter the fluid or to produce a desired direction, velocity, or shape of discharge. Specifically, in gas turbine engines, the nozzle is the aperture through which exhaust gases escape into the atmosphere and in which as much energy as possible is converted into kinetic energy. See exhaust nozzle.
ii. The primary aperture through which fuel is injected into a gas turbine engine combustion chamber.
iii. A duct with a varying cross-sectional area used to accelerate the fluid flow. This acceleration of fluid causes the pressure to decrease.
