Abstract
A constant pressure fluid flow acceleration nozzle system includes a nozzle having a bore, such bore having substantially the geometry of a conical section, the section having an input to the bore and an output therefrom, the input to the bore being larger than the output. The bore is provided with uniformly tapered interior walls, the walls defining a uniform inward radial taper of about one unit of length for every nine units of axial length of the bore. The ratio of the cross-section of the diameter of the input to said bore to the cross-sectional diameter of the output to said bore is preferably about 1.6 to one. Resultantly, increased velocity within the bore, without material increase in pressure is achieved to thereby minimize turbulence and achieve a better fluid distribution.
