三角绕流滴灌灌水器结构设计和优化(Structural Design and Optimization of Triangle Circulation Drip Irrigation Emitters)
灌水器 三角绕流 水力性能
2010/12/28
以三角绕流滴灌灌水器结构的流道单元为研究对象,利用Pro/E软件完成灌水器造型设计,结合计算流体动力学软件Fluent 6.3模拟分析流道的水力性能,研究此类灌水器的湍流特性,揭示其内部湍流流动机理,并对流道结构进行优化。根据分析结果,通过改变外部大三角的形状与内部小三角的形状和位置,对流道单元进行结构优化,得出一种流态指数小于0.5,流道内速度分布均匀,流量在滴灌允许范围内,抗堵性能优良的三角绕...
