vortex core

Angle Function Method is introduced to fairly fast detect vortex core region in flow field.

提出了一种称为“角度函数”的方法来快速检测流场中的涡核区域。

A model is developed for the calculation of the initial rotor tip vortex core radius aiming at eliminating the empirical parameters of the tip vortex in rotor free-vortex wake analysis.

建立了一个旋翼桨尖涡初始涡核半径计算模型，用于消除旋翼自由尾迹分析中桨尖涡涡核半径依靠经验设定的现状。

A new method for measuring precessing vortex core in swirling flow

一种测定强旋流中旋进涡核（PVC）的新技术

The axial velocity has no obvious regular variety, but increases in the vortex core region of the upper part of the cyclone body, and the retention phenomenon in the vortex core region is weakened.

轴向速度没有明显的规律性变化，只在上部筒体涡核区轴向速度增加，削弱了涡核区滞留现象；
