中文摘要设计了一种弹性喷嘴的变量喷头,其喷嘴直径随压力的增大而变大,从而降低喷头的雾化程度。为研究确定弹性喷嘴锥形角、喷嘴直径、末端圆柱段长度、弹性材料厚度和喷嘴伸出量等主要参数,利用ANSYS建立了变量喷头及其内流道的三维实体模型,采用k-ε模型在CFX和ANSYS单向流固耦合中模拟喷头弹性喷嘴在不同工作压力,不同喷嘴直径组合下的内流道流场和喷嘴的变形过程,建立了工作压力、喷嘴直径变形和喷头流量等参数的关系模型。采用全面喷洒的方法对喷头样品进行了试验,通过测量喷头流量和喷头工作压力等,对模拟结果进行验证。
英文摘要A flexible nozzle of the variable-rate sprinkler was developed. As the pressure increased,the
diameter of the flexible nozzle increased and then the degree of fogging reduced. The main parameters of
the nozzle,cone angle,range nozzle,length of end cylindrical section,thickness of elastic material,and
extended volume of nozzle,were investigated. The 3-D solid model of the flexible variable nozzle and its
internal runner were established using ANSYS software. The internal flow field of the flexible nozzle was
simulated using computational fluid dynamics ( CFD) software with k-ε model and ANSYS software with
one-way fluid solid coupling model at different working pressure and different range nozzle. Relationship
between working pressure,range nozzle and nozzle flow were evaluated. Simulation results were verified
and precision of model was improved by measuring the displacement of the nozzle,the nozzle flow and the
working pressure of the produced nozzle samples.
