Abstract (en)

[origin: WO9801231A1] The present invention relates to a method for producing a gas-droplet jet stream, wherein said method comprises the following steps: accelerating a gas flow in a gas-dynamic nozzle; introducing a dispersed liquid flow into said gas flow during the acceleration process of the latter; and accelerating the two-phase flow thus obtained in an injector. The gas pressure at the nozzle inlet and the relative concentration of liquid in the two-phase flow are selected according to predetermined conditions that allow for the generation of gas-droplet jet streams capable of flying over a distance exceeding 50 m. This invention also relates to equipment for generating such gas-droplet jet streams, wherein said equipment comprises liquid and gas supply systems (1, 2) as well as a gas-dynamic nozzle (4). The gas-dynamic nozzle (4) includes a chamber (3) for mixing the gas and the liquid as well as a contoured channel (7). This method may also be implemented using an annular nozzle, while the length of the contoured channel (7) must be equal to at least five times the diameter at the critical section of said nozzle.
