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.
