摘要
本文通过平面理想均匀直线流动和偶极流迭加成为流体对柱体的绕流,阐述了漩涡形成的原理。并以此为基础,分析了有限封闭管道内实际流体形成漩涡的特点,通过分区,推荐了最佳漩涡信号的采集点。
The principle of vortex formation is expounded by analyzing the ideal uniform planar linear flow and the dipole flow which superpose the fluid flow around cylinder.And on this basis,the article analyzes the characteristics of the vortex which is formed by actual fluid in limited closed pipes.Additionally,through partitioning,this paper suggests how to select the best vortex signal acquisition points.
