Correlation analysis on volume vorticity and vortex in late boundary layer transition

In this paper, two functions are introduced to describe the turbulence generation in late flow transition. One is called the volume omega bar (volume Ω¯), which represents the flow rotation or vortex strength. The other is called the volume vorticity, which shows the flow statistical fluctuations. A...
