The de Laval nozzle was originally developed in the 19th century by Gustaf de Laval for use in steam turbines.It was first used in an early rocket engine developed by Robert Goddard, one of the fathers of modern rocketry.It has since been used in almost all rocket engines, including Walter Thiel's implementation, which made possible Germany's V-2 rocket. A de Laval nozzle will only choke at the throat if the pressure and mass flow through the nozzle is sufficient to reach sonic speeds, otherwise no supersonic flow is achieved, and it will act as a Venturi tube; this requires the entry pressure to the nozzle to be significantly above ambient at all times (equivalently, the stagnation pressure of the jet must be above ambient).

The nozzle was proposed in 1890 by the Swedish inventor Gustaf de Laval for steam turbines. In a rocket engine, the Laval nozzle was first used by General M. Pomortsev in 1915. The phenomenon of acceleration of gas to supersonic speeds in the Laval nozzle was discovered at the end of the XIX. Experimental way. nozzle geometry co-ordinates are taken by using of method of characteristics which usually de signed for De-Laval nozzle.

This program is intended to help students of compressible aerodynamics visualize the flow through this type of nozzle at a range of conditions. A de Laval nozzle (or convergent-divergent nozzle, CD nozzle or con-di nozzle) is a tube that is pinched in the middle, making a carefully balanced, asymmetric hourglass shape. It is used to accelerate a hot, pressurized gas passing through it to a higher speed in the axial (thrust) direction, by converting the heat energy of the flow into kinetic energy. Because of this, the nozzle is widely A de Laval nozzle (or convergent-divergent nozzle, CD nozzle or con-di nozzle) is a tube that is pinched in the middle, making a carefully balanced, asymmetric hourglass-shape. It is used to accelerate a hot, pressurized gas passing through it to a higher speed in the axial (thrust) direction, by converting the heat energy of the flow into In real nozzles, the length to throat area ratio is important for keeping the flow attached.
