| 摘 要： | 利用Fluent软件对滴灌灌水器流道内流体流动进行了数值模拟,得到了流道流速分布图,对滴头流道结构进行了优化设计,采用了圆弧形流道结构.通过优化前、后的速度分布图可知:优化后的滴头流道涡旋区和速度滞止区基本消除,虽然在拐弯处的小部分区域内流体流动速度仍然有所偏高,但是从流道整体来看,优化后的流道内主流速度分布较均匀,且...

| Abstract: | Numerical simulation of drip emitter channel by CFD software,obtained the velocity distribute of channel,optimum channel structure design and adoptive the arc structure.Compared with laminar flow,it is found that,the turbulent flow and stagnant region are deleted in the arc channel,although the turning area have higher velocity,but on the whole,the velocity distribute is better-distributed,and full of entire channel,it is enhanced anti-clogging performance of emitter channel. |
