摘要
为提高水射流油管清洗效率,开展了喷嘴结构优化研究。以圆柱形高压水射流喷嘴为研究对象,以油管壁面动压力与壁面切应力为判断喷嘴清洗性能的主要指标,利用计算流体力学(CFD)Fluent分析软件及Solidworks建模软件,对油管清洗高压水射流喷嘴进行三维建模,并进行模拟分析,利用正交实验方法对喷嘴关键结构进行优化。优化结果表明,喷嘴圆锥段收缩角为45°,入口直径为4mm,出口直径为0.5mm,出口圆柱段长度为1mm,喷嘴与轴线夹角90°为喷嘴最佳结构。该研究可为油管清洗方面提供一定的理论与技术参考。
In order to improve the efficiency of water jet for cleaning tubing,the optimal research on the nozzle structure was carried out.Taking the cylindrical water jet nozzle with high pressure as research object and the dynamic pressure and the shear stress of the tubing wall as the main index to judge the cleaning performance of the nozzle,three-dimensional model of water jet nozzle with high pressure for cleaning tubings was established and analyzed by using computational fluid dynamics(CFD)Fluent analysis software and Solidworks modeling software,and the key structure of nozzle was optimized by orthogonal test method.The optimal results showed that the conical shrinkage angle of nozzle was 45°;the inlet diameter was 4 mm,the outlet diameter was 0.5 mm;the outlet cylindrical length was 1 mm;and the 90°angle between nozzle and axis was the best structure.The research could provide some theoretical and technical reference for cleaning tubings.
