Liutex and Third Generation of Vortex Identification Methodsnturies. Liutex is a new physical quantity to represent fluid rotation or vortex, discovered by Liu et al. at University of Texas at Arlington (UTA) in 2018. Liutex is thought as one of the most important breakthroughs in modern fluid dynamics. There are three generations of vortex identification me

Incorrectness of the Second-Generation Vortex Identification Method and Introduction to Liutexthough many experimental results do not support this point of view. Even though scientists do not doubt the correctness of vorticity, they have to develop some other vortex identification methods to improve the performance of detecting vortex. Under this situation, Q method, . method and . method ar

Dimensional and Theoretical Analysis of Second-Generation Vortex Identification Methodsing us to better identify and visualize vortices. The most popular traditional methods taught in educational institutions are ., ∆, . and ., with . being the most popular method used in research and industry. These methods are known as the second generation of vortex identification methods. Although

No Vortex in Straight Flows: On the Eigen-Representations of Velocity Gradient ∇Except the λ. criterion, all these criterions recognize vortices by designing various invariants, based on the Helmholtz decomposition that decomposes velocity gradient into strain rate and spin. In recent years, the intuition of “no vortex in straight flows” has promoted people to analyze the vorte

Mathematical Definition of Vortex Boundary and Boundary Classification Based on Topological Typeween rotation axis and eigenvectors of velocity gradient tensor. Based on this relation, the geometric and physical meanings of Liutex magnitude and the concept of rigid-rotation of vortex are revisited. Considering the simple shear, geometric meaning of Liutex can be explained through geometric rel

Liutex-Based Investigation of Vortex in Multiphase Flow Past 2-D Cylinder Using GPU-Accelerated LBM solid renders the flow characteristics and vortex field sophisticated. In this paper, we employ the GPU-accelerated Lattice Boltzmann Method to study the process of multiphase flow past a 2-D cylinder. The drag force components induced by continuous and dispersed phase respectively as well as the t

On the Comparison of Liutex Method with Other Vortex Identification Methods in a Confined Tip-Leakagze . = 10 mm is performed. TLV cavitation and TSV cavitation are reasonably captured. Different vortex identification methods of all three generations, including vorticity, .-criterion, . method and Liutex method are compared in detail with the simulated tip leakage cavitating results. It is observe
