Abstract: An alignable conformal, cup-shaped flag-mushroom fluidic nozzle assembly is engineered to generate a flat fan or sheet oscillating spray of viscous fluid product 316. The nozzle assembly includes a cylindrical flag mushroom fluidic cup member 180 having a substantially closed distal end wall with a centrally located snout defined therein. The flag mushroom cup assembly effectively splits the operating features of the fluidic circuit between a lower or proximal portion formed in the housing's sealing post member and an upper, or distal portion formed in cup member 180 which, in cooperation with the sealing post's distal surface, defines an interaction chamber 192 fed by impinging jets each comprising a continuous distribution of streamlines that impinge at selected angles to define arcs providing a lesser degree of impingement at a centered axial plane within the exit orifice 194 and a greater degree of impingement at the edges of exit orifice 194.

Abstract: A clog resistant online vortex emitter assembly and method uses a double-sided circuit and a series of vortex chambers of optimized dimensions to create a pressure drop with large dimensions and good clog resistance. The vortex emitter allows for pressure regulation without moving parts and includes a unitary body having a first surface and a second surface opposite the first surface and a multi-lumen flow channel providing fluid communication between the first surface and the second surface, wherein said unitary body is a double-sided circuit with a plurality of vortex chambers with lumens aligned in series. The vortex chamber includes an inlet region, a power nozzle, an interaction region and a throat, the inlet region is in fluid communication with the interaction region through the power nozzle. The plurality of vortex chambers includes dimensions to create a pressure drop and be attached to an outer surface of an irrigation tube.

Abstract: A clog resistant in-line vortex emitter and drip irrigation assembly and method uses a double-sided circuit and a series of vortex chambers of optimized dimensions to create a pressure drop with large dimensions and good clog resistance. The vortex chamber 100 also allows for a lower exponent than traditional circuits. This gives a pressure regulating property to the no-moving-parts circuit. The vortex emitter allows for some pressure regulation without sacrificing recyclability or requiring moving parts. The vortex circuit of the present disclosure is optimized for an emitter efficiency Ef value wherein Ef=(k/Ackt)*Amin such that k is a unitless head loss coefficient, Ackt is the area of the circuit, and Amin is the minimum cross sectional area of the circuit. A higher k per a given area with larger dimensions allows for a smaller part with a lower chance of clogging.

Abstract: A flow-restricted compound spray generating device 100 includes a spray face member 120B including at least one fluidic circuit oscillator defining geometry 132 including an outlet orifice 138 in the spray face member's central area configured to aim an oscillating spray 300 having a selected oscillating spray thickness distally along a spray axis 112. The spray face member 120B also includes a plurality of non-oscillating (e.g., laminar or jet) spray generating orifices 160B arrayed evenly around the spray face member's periphery to aim a plurality of non-oscillating laminar or jet sprays 302 distally along the spray axis 112 to provide a ring of high velocity streams arrayed around the central oscillating spray 300 to generate a compound spray 310 with an outflow which has a pleasing spray density with an apparent outflow thickness which is substantially equal to the spout orifice's diameter 320.
