Research and Development of Rotary Sprinkler Hydraulic Characteristics of the External Flow Field

Abstract

Sprinkler key equipment is the irrigation system in sprinkler hydraulic characteristics of the external flow field. It is also an important indicator in performance evaluation of the sprinkler. It is a literature review that the progress of the recent research in the field of hydraulic characteristics of the outflow nozzle is reviewed in this paper, including the test and numerical simulation of droplet trajectory, the distribution of water droplets based on different factors, the uniformity of water distribution and its impacts on the construction of water distribution model and dynamic simulation. The basis of analysis in this research was to analyze the problem of the hydraulic characteristics of the nozzle outflow field and look at the nozzle trends and methods of the hydraulic characteristics of the field for future outflows sprinklers.
