Abstract
Disclosed is a design method for a three-dimensional special-shaped jet nozzle used in the field of water-saving irrigation in farmland. According to a method based on a gas-liquid two-phase flow theory and computational fluid dynamics (CFD), a fan-shaped jet mode and a beam-shaped jet mode are coupled according to a certain area ratio and velocity ratio, which enables a cylindrical-conical coupling structure to be presented all the way from an inlet to an outlet of the nozzle, and a jet orifice is optimally designed into a three-dimensional special-shaped slotted structure; along a flowing direction of the jet orifice, V-shaped slots are formed in bottom and front portions of a midperpendicular plane, where a fan-shaped jet capable of forming a near-range water body prevails, and a strip-shaped slot is formed in an upper half portion of the midperpendicular plane, where a beam-shaped jet capable of forming a far-range water body prevails; and the V-shaped slots and the strip-shaped slot promote the formation of a narrow-band range S in a synergistic manner due to smooth joint transition therebetween. The present disclosure is particularly suitable for farmland sprinkling irrigatio…
