  • Jetting nozzle
    Patent number: 5056718
    Abstract: A jetting nozzle for producing a high velocity fluid has its external surface formed as a fluidic surface and directs a second lower velocity jet of fluid, which may be the same as or different from the fluid of the high velocity jet, onto the external surface such that the fluid of the second jet flows in contact with the fluidic surface to surround the high velocity jet, thereby reducing the rate of divergence of the high velocity jet preserving its energy and increasing its effective range.
