            DATA FROM DNS OF IMPINGING SHOCK WAVE BOUNDARY
                      LAYER INTERACTION (M = 2.28)

This directory contains files where Favre averages are stored. These fields
are two-dimensional, being the flow statistically homogeneous in the
span-wise direction. Files are directly readable by Tecplot.

The parameters of the simulation are

Free-stream Mach number ====> M = 2.28
Reynolds number based on the inlet BL thickness ====> Re = 16750.
Incidence angle of the shock generator ====> phi = 8 degree
gamma = 1.4 

Favre averages are stored in formatted files named "favre_ib.dat", which
also contains grid coordinates. The index "ib" refers to a specific block
of the grid. The computational domain is subdivided into 64 blocks along the
stream-wise direction (x coordinate). The wall-normal direction
is indicated with y. 
The overall size of the domain is 80.58 in the stream-wise direction (x),
12.89 in the wall-normal direction (y)
The reference length is the boundary-layer thickness
at the inlet section (x=0).
Each block consists of nx = 61 X ny = 344 points uniformly
distributed in the x direction and clustered towards the wall.
The last point of each block coincides with the first one of the following
block. Files can be read as

where arrays x and y contain grid coordinates.
The order of variables in the array favre is the following

 m  variable
------------
 1  x
 2  y 
 3  u
 4  v
 5  u'' v ''
 6  u'' u ''
 7  v'' v ''
 8  w'' w ''

where u, v, w are the velocity components and the double prime '' indicates
fluctuations with respect to the Favre averaging.

All variables are nondimensional. The reference density, pressure,
temperature and velocity are taken to be the free-stream values.
