NUMERICAL AND EXPERIMENTAL STUDY ON TURBULENCE PRODUCTION OF A SELECTED MODE OF STREAMWISE VORTEX INTERACTION IN SUPERSONIC FLOW
(2019-05-10)
The development of effective mixing strategies of air/fuel mixtures in supersonic flows has been the subject of a significant body of research for the last 60 years due to the hindering effects of compressibility. Particular ...
Observation of the Interaction Between a Transonic Shock Wave and a Wingtip Vortex
(2018-12-04)
The present study observes the interaction between two fundamental phenomena in fluid mechanics: the transonic shock wave and the wingtip vortex. While these are two areas of fluid mechanics in which extensive experimental ...
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, ...
LIUTEX AND STATISTICAL ANALYSIS FOR FLUID TRANSITION
(2021-08)
A vortex can be intuitively recognized as the rotational swirling motion of the fluids. The fascination of this phenomenon brought about many years of research to define, classify, and identify the vortical structure. ...
HIGH ORDER DNS FOR VORTEX STRUCTURE IN LATE FLOW TRANSITION
(2017-08-02)
Turbulence is still a world puzzle after over one hundred years research, and the current and classical theories brim with self-contradictions. C. Liu proposed a new theory on turbulence generation and structure after 28 ...
