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. The nozzle assembly includes a cylindrical flag mushroom fluidic cup memberhaving 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 memberwhich, in cooperation with the sealing post's distal surface, defines an interaction chamberfed 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 orificeand a greater degree of impingement at the edges of exit orifice

A flow-restricted compound spray generating deviceincludes a spray face memberB including at least one fluidic circuit oscillator defining geometryincluding an outlet orificein the spray face member's central area configured to aim an oscillating sprayhaving a selected oscillating spray thickness distally along a spray axis. The spray face memberB also includes a plurality of non-oscillating (e.g., laminar or jet) spray generating orificesB arrayed evenly around the spray face member's periphery to aim a plurality of non-oscillating laminar or jet spraysdistally along the spray axisto provide a ring of high velocity streams arrayed around the central oscillating sprayto generate a compound spraywith an outflow which has a pleasing spray density with an apparent outflow thickness which is substantially equal to the spout orifice's diameter

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 al lows 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.
