De Laval nozzle

A de Laval nozzle (or convergent-divergent nozzle ,CD nozzle or con-di nozzle ) is a tube that is pinched in the middle, making an hourglass-shape. It is used as a means of accelerating the flow of a gas passing through it to a supersonic speed. It is widely used in some types of steam turbine and is an essential part of the modern rocket engine and supersonic jet engines Similar flow properties have been applied to jet streams within astrophysics.
