A fluid flow nozzle is provided that comprises an elongated body having an inlet end and an outlet end, and defining a channel extending therethrough in which the channel includes an inlet channel and an outlet channel having an outlet diameter that is less than the inlet diameter. The channel further defining a tapered channel extending from the inlet channel to the outlet channel with a plurality of vanes or grooves circumferentially spaced around the tapered channel to increase flow velocity while reducing turbulence and divergence of the discharge stream.
