The invention related to producing a gas-drop jet, in particular a high-concentration two-phase jet containing fluid drops or solid particles in a gas flow. Said type of jets can be used for fire prevention engineering, agriculture for watering or climatic plants, for abrasive processing devices, and for other engineering fields using similar jets. The technical result is achieved by the inventive method for producing a two-phase gas-drop jet consisting in accelerating a two-phase flow up to a velocity equal to or higher than the speed of sound in the two-phase flow, the pressure thereof being reduced to a pressure which is higher than the efflux medium pressure. The inventive method makes it possible to produce a positive pressure increasing the two-phase flow spray angle. The technical results is also achieved by the inventive device for producing a high-concentration gas-drop jet comprising a gas-dynamic nozzle which is embodied in such a way that it consists of two parts, one of which being arranged with respect to the other in such a way that it is removable from the jet. |
