Abstract
An optimization design method for a spatial flow passage of a low-pressure even spray nozzle, relating to a design method for an essential apparatus in a water-saving irrigation system, such as a spray irrigation system. Specifically, if the model and the inlet diameter of a nozzle are determined, the shape and the size of the cross section of an outlet, a flow passage deflection angle, the radius and the arc length of a flow passage contour, and the size of an elevation angle of the outlet are determined to implement structural optimization of a spatial flow passage of the nozzle; moreover, parameterization design of the spatial flow passage in different inlet diameter conditions is implemented, so that a method for determining structural parameters of a spatial flow passage of a nozzle is obtained. A design method of a spatial flow passage under a low-pressure operation condition is developed, such that the hydraulic performance of the nozzle is optimized, and the nozzle is efficient and saves energy.
