Abstract
With the shortage of water resources in China, water-saving agriculture has been highly addressed and developed by the government. This paper studies the channel structure of a helical micro pressure drip irrigation emitter, focusing on the tilt and tooth chamfer’s angles within eight different combinations of structure parameters. By comparison of hydraulic performances, it show a small discrepancies between CFD software simulating results and testing results on 6 selected real trial prototype samples of flaky emitters and inlaid drip pipes. A conclude is made that under various flow coefficient K and pressure sensitive coefficient X, in the section of minimum flow, the smaller angle the better hydraulic performance, the bigger angle r the better anti clogging ability.
