How does a de Laval (convergent-divergent) nozzle work? There is a relatively simple equation that you can use to calculate the throat area of the nozzle 'A*' Gas flow through nozzles - sonic chokes. Sponsored Links. The maximum gas flow through a nozzle is determined by critical pressure. critical pressure ratio is The nozzles which perform this feat are called DeLaval nozzles (after the inventor ) and consist To understand this we must examine the basic thrust equation: Eliminating density and pressure yields an equation for the Laval nozzle.

2018-04-26 2021-04-15 Such nozzles are called de Laval nozzles and in extreme cases they are able to reach hypersonic speeds (13 Mach at 20 °C). Mach number - Wikipedia The most commonly used nozzle is the de Laval nozzle, a fixed geometry nozzle with a high expansion-ratio. A convergingdiverging nozzle ('condi' nozzle, or CD- -nozzle), is the only one to get supersonic flows with M >1 (when chocked). It was developed by Swedish inventor Gustaf de Laval in 1888 for use on a steam turbine. Supersonic flow in CD-nozzles presents a rich behaviour, with shock waves and expansion nozzle wall through a sharp corner while in (12) the com bined throat and nozzle contour is required to have con tinuous slope. In (8) and (12) the authors consider the design of optimal De Laval nozzle profiles only. Trulin (16) modifies the formulation and employe the same variational method to obtain optimal expansion-deflection nozzles.

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.

De Laval nozzle 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. In addition, the pressure of the gas at the exit of the expansion portion of the exhaust of a nozzle must not be too low.

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.
