An improved fluid mixing nozzle (10) and method, in which a first fluid flow s therefrom to mix with a second fluid external the nozzle, for inducing vorte x creation and chaotic turbulent flow. The nozzle (10) has a body (20) with a cavity (26) extending therethrough from the inlet end (22) to the outlet end (24). The cross-sectional area of the inlet orifice (30) of the nozzle (10) is greater than its outlet orifice (40) cross-sectional area. The outlet orific e (40) cross-sectional shape has a substantially circular central portion (42) and at least one (but typically more than one) protrusion (50) extending fro m the perimeter of the central portion (42). Generally, the protrusions (50) a re smaller in cross-sectional area than the central portion (42), are equally spaced about the central portion (42) perimeter, and have a length to width ratio from 1 to 2. Functionally applying the above described nozzle (10) is a method of improved mixing, of creating chaotic turbulent flow, and of induci ng vortex creation.
