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

This directory contains files where Reynolds 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 

Reynolds averages are stored in formatted files named "reynolds_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

The order of variables in the array reynolds is the following

 m  variable
------------
 1  x
 2  y 
 3  rho
 4  u
 5  v
 6  p
 7  T
 8  rho'rho'
 9  u'u'
10  v'v'
11  w'w'
12  u'v'
13  p'p'
14  T'T'

where rho is the density, u, v, w are the velocity components,
p the thermodynamic pressure, T the temperature and the prime '
indicates fluctuations with respect to the Reynolds averaging.

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