Table Contents
1.	Governing equation and DNS code
2.	Orr-Sommerfeld equation and its solution
3.	Vortex structure visualization by lambda 2 and 
vortex filaments
4.	Spanwise vortex formation by transfer from shear to 
rotation
5.	Shear layer stability analysis (Shear layer 
instability is the mother of turbulence)
6.	Lambda vortex root formation (Lambda vortex is not a 
vortex tube, but rotation cores) by the spanwise vortex and 
3-D T-S wave which is extremely unstable
7.	Ring like vortex formation which is not part of  
Lambda vortex (There is no such a process that the Lambda 
vortex self-deforms to hairpin vortex; lambda roots and 
vortex rings are developed separately by different 
mechanisms)
8.	Role of unstable modes (push up vorticity from the 
wall, stimulate the transition from shear to rotation, but 
cannot form vortex by themselves) 
9.	Mechanism of multiple vortex ring formation (There 
is not vortex breakdown and reconnection) - all are formed 
by shear layer instability which is generated by momentum 
deficit caused by vortex ring ejection 
10.	U-shaped vortex (Not secondary but tertiary) 
11.	Large vortex structure (Very stable structure and 
cannot break down)
12.	Sweeps, ejections, positive and negative spikes, and 
high shear layers in turbulent flow
13.	Small length scale generation (Not by vortex 
breakdown, but  all are generated by shear layer instability 
which is formed  by positive and negative spikes no matter 
how to define "vortex")
14.	Energy transfer paths from larger vortex to smaller 
vortex (Not by vortex breakdown but by vortex ring sweeps)
15.	Flow Chaos (Not only by background noises but mainly 
by instability of  multiple vortex package structure) 
16.	Richardson eddy cascade revisit (There is no such a 
cascade)
17.	Kolmogorov hypothesis revisit (There is no vortex 
breakdown and there is no energy passing through vortex 
breakdown. There is no proof of existence of Kolmogorov 
small scale)
18.	Flow transition and turbulent flow control (Control 
the shear layers)
19.	Intermittence revisit (There is no intermittence in 
turbulence)
20.	Turbulence model revisit (Model the vortex packages 
and relative motion between packages)
