Liutex and Third Generation of Vortex Identification Methodse second generation of vortex identification. They are all based on the eigenvalues of the velocity gradient tensor. However, they are all scalars and thus strongly threshold-dependent, which have problems with uniqueness and wrong dimension. In addition to lack of physical meanings, they are all co作者: 音樂會 時間: 2025-3-22 08:31 作者: 斜谷 時間: 2025-3-22 11:09
Mathematical Study on Local Fluid Rotation Axis: Vorticity is Not the Rotation Axisa mathematical study on five local fluid rotation axis candidates. Namely, the symmetrical tensor’s three eigenvectors, the vorticity vector, and the Liutex directional vector. The results show that the vorticity vector satisfied the local fluid rotation axis requirements only in particular cases.
