LIUTEX ANALYSIS BY POD AND DMD IN TURBULENT FLOW AFTER/ IN MICRO VORTEX GENERATOR
(2021-12-06)
Although vortex has been studied more than one hundred year, we still have not had universally accepted definition. A few well-known vortex identification methods are introduced 𝑄,∆, 𝜆2,𝜆𝑐𝑖 criteria to identify coherent ...
LIUTEX ANALYSIS BY POD AND DMD FOR VORTEX FORMATIONS IN BOUNDARY LAYER TRANSITION
(2019-12-05)
Vortices are considered as the building blocks of turbulent flows. To study how one type of vortex becomes another type especially in flow transition is one way to get better understanding about turbulence. In this ...
MATHEMATICAL APPROACH OF LIUTEX CORE LINE AND LIUTEX CORE TUBE FOR VORTEX STRUCTURE VISUALIZATION
(2021-06-10)
During the past decades, many vortex identification methods have been published to present a clear definition and identification of the vortex. However, all these methods are failed to offer a unique identification method, ...
Mechanism of Hairpin Vortex Formation by Liutex
(2023-05-11)
Turbulence is still a mystery for human after more than one century’s development of fluid dynamics. Hairpin vortex formation is regarded as an essential process for a laminar flow transition to the turbulent flow. A new ...
Large Eddy Simulation by using Wang’s Liutex-based subgrid model
(2023-08-09)
Turbulent flows and vortex structures in fluid dynamics have been captivating researchers for decades, owing to their intrinsic complexity and significance in various industrial and natural processes. Despite their fundamental ...
