Firstly, an investigation focuses on the aerodynamic properties of this jet that streamed through the plasma torch De-Laval nozzle and impinged optical surfaces. Secondly, the work highlights quantitatively the effects of changing the distance between the processed surface and nozzle outlet. In both ...

de Laval nozzles are mechanical devices which are used to convert the thermal and pressure energy into useful kinetic energy. The values of temperature, pressure and velocity should be available at every section of the nozzle so as to design the nozzle shape, insulation and cooling arrangements....

A de Laval nozzle is constituted by an hour-glass-shaped tube, strained in the middle, utilized to accelerate a hot pressurized gas to a high supersonic speed into the thrust direction. The fluid thermal energy is com- muted into kinetic energy, and the fluid velocity increases. The energy...
( 20 ) adapted to act as a burner at subsonic or supersonic speed, combined with a plurality of nozzles ( 31, 32 ) for fuel and comburant respectively, arranged in two rings, concentric and co-axial to said De Laval nozzle ( 20 ) and externally protected by a specifically shaped ...
