ABSTRACT:
The invention relates to a method and apparatus for creating a fluid screen for use in entertainment. Provided is a mechanically simple and effective way of creating a fluid screen which facilitates the projection of still and moving pictures upon it. The fluid screen is generated by pumping water, or other comparable fluid, through a fluid screen nozzle having an axial flow director and a nozzle insert. The fluid, at a given pressure and flow rate, is directed through the axial flow director, past the internal end of the nozzle insert and its transition section and then onto and away from its radial stabilizer. The fluid is guided by the radial stabilizer of the nozzle insert to form the fluid screen. Each of the regions mentioned contribute to creating the desired shape of the projection surface. Performance may be further enhanced by having a flow straightening area adjacent to the axial flow director, a reducer prior to the nozzle insert, and texturing the surfaces of the transition section and radial stabilizer.
