    摘要:

    文中提出了基于特征流场[1]概念的平面时变流场多涡结构中涡旋的自动提取及跟踪算法研究。该算法是通过提取流场中的涡旋区域从而确定涡核范围,对涡核采用流线积分的方法来跟踪,精密跟踪三维特征流场内涡核以及在被积流线上记录其具体的演化路径,从而为流场中不同时段的演变过程能更直观的去观察奠定了基础。

    Abstract:

    Based on Feature Flow Fields[1], vortex will automatically extract and track in a flat time-varying flow field and multi-vortex structure. The new algorithm is to extract the vortex areas of flow field to determine the vortex core range, using the method of tracking the vortex core flow line integral, precision tracking vortex core in the three-dimensional feature flow field and recording the specific path of evolution in the integrand flow line. Thus for the flow field in the different periods of evolution can be observed directly laid the foundation.used for tracking the vortex core flow line integral, by extracting the vortex areas of flow field to determine the vortex core range, precision tracking vortex core in the three-dimensional feature flow field and recording the specific path of evolution in the integrand flow line. The new algorithm using the flow line can describe the dynamic behavior of characteristics of vector field. The evolution of the flow field is more intuitive to observe the evolution of different periods, which laid the basis for visualization.
