This directory contains the following files:

frame3.dat............2D-PIV data at centerplane of tunnel from x/c approx 0.89 to x/c approx 1.11
                      at phases 0, 10, 20, ..., 350, 360 (360 is a repeat of 0)

The data given are:
    x/c      = x-location, normalized by hump chord (c=0.4200 m)
    y/c      = y-location, normalized by hump chord (c=0.4200 m)
    Umean    = mean x-component of velocity in m/s
    Vmean    = mean y-component of velocity in m/s
    Urms     = u_rms=u' in m/s
    Vrms     = v_rms=v' in m/s
    UV       = -u'v' in m^2/s^2
    Npoints  = how many "good" measurements were made at particular x,y location

Regarding the Phase, the time at which peak BLOWING velocity was measured OUT
of the slot corresponds to approximately Phase=170 deg.

Note that this file includes a small region at the bottom left corner
that lies INSIDE of the hump body.  (The coordinates for the
hump body at its back end are given in the file coords_backend.dat.)
The data in frame3.dat that lie within this region should be
discounted.  Also, data within a distance of .004c - .005c of the
wall is likely unreliable (due to wall reflection) and should also
be discounted!

Using a convergence analysis, a conservative estimate on the maximum error 
of the turbulence data is 16%.  Therefore, the turbulence data given
here should not be taken as absolute levels, but rather should be used to 
assist in qualitative evaluation of turbulence models.



The data files are all "Tecplot-format" (version 10).
For example, for:

 I=96, J=70, K=1, ZONETYPE=Ordered
 DATAPACKING=BLOCK

the data can be read from a given section via:

      idim=96
      jdim=70
      read(2,*) ((x(i,j),i=1,idim),j=1,jdim)
      read(2,*) ((y(i,j),i=1,idim),j=1,jdim)
      read(2,*) ((u(i,j),i=1,idim),j=1,jdim)
      read(2,*) ((v(i,j),i=1,idim),j=1,jdim)
      read(2,*) ((uprime(i,j),i=1,idim),j=1,jdim)
      read(2,*) ((vprime(i,j),i=1,idim),j=1,jdim)
      read(2,*) ((upvp(i,j),i=1,idim),j=1,jdim)
      read(2,*) ((points(i,j),i=1,idim),j=1,jdim)
