To reduce the power requirements, supercritical car- The analysis of gas flow through de Laval nozzles involves a number of concepts and assumptions: For simplicity, the gas is assumed to be an ideal gas. The gas flow is isentropic (i.e., at constant entropy ). As a result, the flow is reversible (frictionless and no The gas flow is constant (i.e., Se hela listan på engineering.fandom.com A de Laval nozzle (or convergent-divergent nozzle) features a length of tube pinched in the middle (the throat). At subsonic velocities a converging tube causes the gas flow to accelerate.
The invention relates to a Laval nozzle for thermal spraying and kinetic spraying, especially for cold gas spraying, with a convergent section and a divergent

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.

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.

A de Laval nozzle (or convergent-divergent nozzle) features a length of tube pinched in the middle (the throat). At subsonic velocities a converging tube causes the gas flow to accelerate. At supersonic velocities, however, the tube must be divergent in order for the gas to expand and accelerate.
It is used to accelerate a hot, pressurized gas passing through it to a higher supersonic speed in the axial (thrust) direc De Laval Nozzle. In 1882 he introduced his concept of an impulse steam turbine and in 1887 built a small steam turbine to demonstrate that such devices could be constructed on that scale. In 1890 Laval developed a nozzle to increase the steam jet to supersonic speed, working off the kinetic energy of the steam, rather than its pressure. 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 supersonic speed in the axial (thrust) direction, by converting the heat energy of the flow into kinetic energy. But, if you just used the final diameter of the inside of the housing as the de laval outlet diameter, and considered the housing to be part of the nozzle, you could probably make it work.
