Vortex definition and identification are extremely important for the study of fluid dynamics research. Liutex is a newly proposed concept that correctly represents vortex. vector whose direction local rotation axis magnitude twice angular speed. To identify unique structure vortex, method known as Core Line has been developed, which displays rotational core However, original manual method, not practical real application, an automatic algorithm required usage. Xu et al. by selecting best line from group candidate lines, progress. In this chapter, another perspective to solve problem, new introduced based on forward gradient lines. Since lines have feature they advance maximums, route will still result in line, avoids process find line. This achieved some success Lambda vortex early boundary layer transition.
