三向分叉流道灌水器开发与水力性能模拟研究
Development of Three-Way Bifurcated Flow Channel Irrigator and Hydraulic Performance Simulation Research
摘要
Abstract
In order to explore the influence of water diversion angle and water blocking angle on the hydraulic performance of three-way bifur-cated flow channel emitters,the numerical simulation method was mainly used,and the numerical simulation was carried out with the help of Fluent software,and then the flow field was visualized by Tecplot software.Taking the three-way bifurcated flow channel emitters of 10 flow channel units as the research object,the water diversion angle and the water blocking angle were the two structural influencing factors of the study.The simulation study was carried out by drawing 15 groups of models under different flow channel parameters,and the hydraulic per-formance of the labyrinth flow channel was optimized by adjusting the water diversion angle and the water blocking angle.The results show that:a)With the increase of the diversion angle,the water blocking angle also increases,the flow coefficient of the labyrinth channel de-creases significantly,and the flow state index also decreases.The change of the diversion angle will lead to the change of the water flow distri-bution.b)With the increase of the water blocking angle,the flow coefficient of the labyrinth flow channel also increases,and presents a line-ar change,and the flow state index also increases gradually with the increase of the water blocking angle.c)In the labyrinth channel with different water diversion angles and different water blocking angles,the blocked particles are easier to discharge.However,the maximum ve-locity of the blocked particles in the labyrinth channel with different diversion angles is different.The larger the diversion angle,the greater the maximum velocity of the blocked particles in the labyrinth channel.The hydraulic performance and anti-blocking performance of the three-way bifurcated channel emitter are excellent.关键词
