Abstract

Based on parametric design of curves using data points, two novel hydrocyclones were designed: Spline-Curved-Cone hydrocyclone (H2) and Expassoc-Curved-Cone hydrocyclone (H3). These designs are improvements on the traditional biconical hydrocyclone (H1). Numerical simulations and experimental validation by PIV measurement were used to investigate the effects of cone section profiles on the flow characteristics and separation efficiency. The results showed both H2 and H3 achieved higher separation efficiency than H1. Specifically, the highest efficiency of H3 increased by 24.71 %, and that of H2 increased by 16.22 % compared with H1. It was also found the curved design of cone section profile directly affects the tangential velocity distribution and pressure distribution of the flow field inside hydrocyclones. H3 exhibited better flow field stability and highest separation efficiency due to its optimized cone section space and flow structure. This study provides scientific basis and data support for the optimization and industrial application of the cylinder-on-cone hydrocyclones.

使用数据点的曲面水力旋流器参数化设计及其分离强化机制

根据使用数据点的曲线参数设计，设计了两种新型水力旋流器：Spline-Curved-Cone 水力旋流器 (H2) 和 Expassoc-Curved-Cone 水力旋流器 (H3)。这些设计是对传统双锥水力旋流器（H1）的改进。通过数值模拟和 PIV 测量进行实验验证，研究了锥体截面对流动特性和分离效率的影响。结果表明，H2 和 H3 的分离效率均高于 H1。具体来说，与 H1 相比，H3 的最高效率提高了 24.71%，H2 提高了 16.22%。研究还发现，锥形截面的曲线设计直接影响水力旋流器内部流场的切向速度分布和压力分布。由于优化了锥体截面空间和流动结构，H3 表现出更好的流场稳定性和最高的分离效率。这项研究为圆筒-圆锥水力旋流器的优化和工业应用提供了科学依据和数据支持。
