Supersonic turbulent mixing layers.
   
       TEST  case SHL22


The directories Mach14 (which contains the data of the Mc=0.525 mixing
layer), Mach16 (which contains the data of the Mc=0.535 mixing layer)
and Mach2 (which contains the data of the Mc=0.64 mixing layer) contain
the same generic files.

The file ``caract.dat'' contains different values and parameters
allowing to normalize the data:

**** U1 is the external supersonic velocity

**** U2 is the external subsonic velocity. Then DU=U1-U2

**** Yref is the location where U(Yref)=Y((U1+U2)/2)

**** Dw is the vorticity thickness Dw=DU/(dU/dY)max,

**** Dstan is the Stanford thickness:
		Dstan=y(U2+SQRT(.9)*DU) - y(U2+SQRT(.1)*DU)

**** B10% is the thickness such:
		B10%=y(U2+.9*DU) - y(U2+.1*DU)

**** Theta is the momentum thickness

The generic name of the files is ``m*_x$.dat''
where *=1,2 or 3 corresponds to the order of the moment of the
velocity (in m^*/s^*) and $ corresponds to the section of the
measurements. Y is the vertical distance in mm (Y=0 mm is on the
separating plate).

For example, the file ``m3_x125.dat'' contains the third order
moment of the velocity for the measurements at the section X=125 mm from
the trailing edge of the separating plate (X=0 mm corresponds to the
trailing edge). 


For the directory Mach3, there are some differencies.
That directory contains the data of the Mc=1. mixing layer.
The generic name of the files is ``m*_x$.dat''
where *=1,2,3,3b,4 or 4b with the same convention except that when
*=3b or 4b, it corresponds to respectively the skewnesses and the
flatnesses of the two components of the velocity.

$ corresponds to the section of the measurements.

WARNING: all data are now in nondimensional and Y*=(Y - Yref)/Dw is the
nondimensional coordinate.

The file ``caract.dat'' contains the same parameters as before.

In that directory, the two new files ``moms_x2.dat'' and
``moms_x10.dat'' contain the data of respectively the section X=2 mm
and X=10 mm (sections very close to the trailing edge). 
	
	The directory Clim contains the measurements in the boundary
	layer at X=-15 mm. The file ``ubar.dat'' contains the mean
	longitudinal velocity; the file ``fluctu.dat'' contains the RMS
	values and the shear stress. The other file ``frottem.dat''
	contains the profile of the normalized turbulent friction. The
	file ``romu.dat'' contains the profiles of the density
	(in kg/m3) and the dynamic viscosity (in kg/(m.s)).

Remark:
the first lines of each file explain the data following in that file.
