报告内容摘要:

Recently, Liutex is proposed for vortex definition and identification. Liutex is a mathematical definition of the rigid rotational part of fluid motion, including consistent definitions of scalar, vector and tensor forms. Liutex overcomes many issues associated with the currently popular vortex identification methods. Based on the concept of Liutex, Liutex line, Liutex magnitude iso-surface, Liutex-Omega method and Liutex core line method are presented to visualize and identify coherent structures in transitional and turbulent flows. Furthermore, the newly discovery of Liutex similarity implies its important role in turbulent flows and its potential for turbulence modeling.
