微灌长流道灌水器结构特性的研究综述

Review of structural characteristics analysis of the long-path emitters for microirrigation

针对微灌长流道灌水器的发展过程,分别从理论分析、试验研究、数值模拟三个角度总结了国内外诸多学者对长流道灌水器结构特性的研究状况,在此基础上提出基于平台技术的灌水器快速开发路线并分形其可行性,从此路线中引出基于特征参数提取的试验方案,并结合当前微小流道的研究思路对迷宫型长流道灌水器的研究方向提出了若干建议,有助于今后快速研发出性能优良的迷宫型长流道灌水器。

Considering the development trend of long-path emitters, this paper reviews the analyses of the long-path emitters conducted by many scholars at home and abroad from such three respects as theoretical analysis, experimental study and numerical simulation. In the light of that, the rapid development approach to emitters based on relevant platform technology was presented and its feasibility was analyzed. Some experimental schemes were proposed on the basis of characteristic parameters extraction. Focused on the research directions of labyrinth long-path emitter, some suggestions combined with study methods on microchannel were presented, which would be helpful to develop high quality emitter products.
