A method for producing a fluidic device (2) for exciting an oscillating jet (12) of predetermined oscillation and mixing characteristics. The fluidic device (2) includes a chamber (4) having a fluid outlet (6) longitudinally displaced from a fluid inlet (8). The fluid inlet (8) is disposed such that in use the fluid (10) entering the chamber (6) through the fluid inlet (8) separates from the inner surface of chamber (4) to excite an oscillating jet (12). The method includes the step of configuring the geometry of the shape and/or dimensions of the cross section of the fluid inlet (8) to determine the mode of oscillation and mixing characteristics of the oscillating jet (12). A fluidic device (2′) for exciting an oscillating jet (12′) whose characteristics can be determined to meet operational requirements.
A method of producing a fluidic device for exciting an oscillating non-precessing jet of predetermined oscillation and mixing characteristics, the fluidic device including a chamber having a fluid inlet disposed such that in use fluid entering the chamber through the fluid inlet separates from the inner surface of the chamber to excite a fluidic jet, said method including the step of selectively configuring the fluid inlet to have a non-circular cross-section to cause said fluidic jet to oscillate in a non-precessing manner and produce said oscillating non-precessing jet of predetermined oscillation and mixing characteristics.
