Lagrangian Liutex this study. The capability of the new methods to educe vortices in geophysical Bickley jet flow is discussed in detail. It is found the Lagrangian version surpasses vorticity-based methods as it is free from shear contamination, and also reveals the Lagrangian nature of vortices. The objective vers

Visualizing Liutex Core Using Liutex Lines and Tubesortex, the vortex core center, the size of the vortex core, and the vortex boundary. A vortex core is defined as a concentration of Liutex vectors. It would be nice if we could visualize the Liutex core to gain a better understanding. In this paper, we will use the Liutex core lines and Liutex tubes

Analysis of Difference Between Liutex and k of the λ. criterion is the contamination by shear. In this paper, the theoretic analysis of difference between Liutex and λ. is presented, from the perspective of the eigensystem of the velocity gradient tensor. It is found that λ. is actually a measurement of angular speed in the non-orthonormal

Hairpin Vortex Formation Mechanisms Based on LXC-Liutex Core Line Method Reynolds number range is 250 < . < 438. It is found that the hairpin vortex can be evolved from a spanwise vortex. A new hairpin vortex can also be formed from a pair of streamwise vortices. Besides, a younger hairpin vortex may be generated from the primary hairpin vortex. Apart from these three w

Liutex in Vortex Statistics of 2D Turbulent System different turbulent systems investigated: (1) 2D turbulence; (2) the weak flow of the a circular cylinder placed near a wall in 2D channel; (3) 2D turbulent thermal convection. The results of vortex statistics for all cases show that the algebraic number density n(A) ∼ A., where A is vortex area. I

Liutex and Proper Orthogonal Decomposition for Coherence Structure in the Wake of Micro Vortex Generr, all the existing vortex identification methods are just a scalar and they are contaminated by shear. For the first time in history, a new vortex vector with both local rotation axis and rotation strength - called Liutex (with no shear) was introduced by Liu et al. in 2018. In this study, we load

Study on the Formation and Evolution of Asymmetrical Vortex Structures in the Late Transitional Bounation) of compressive fluid flow at Mach 0.5 on a flat plate, with only TS waves as input in the inlet (without additional asymmetric perturbations such as suction and blowing at wall boundary) is conducted to investigate nonlinear growth of the large vortex structures in the late transitional bound

Experimental Studies on Vortex Structures Based on MSFLE and Liutexmerging in the turbulent boundary layer of a rectangular channel. Through experiments, the change of the vortex structures over a period of time can be obtained, due to the measurement system moves at a constant speed that similar to the moving velocity of the vortices. And the continuous long expos
