frame1.dat............2D-PIV data at centerplane of tunnel in close-up region near slot
                      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 in m/s
    Vrms     = v_rms 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.

The coordinates for the entire hump body are given in the file coordsnondim.dat.
Note that PIV data within a distance of about .0012c of the
wall is likely unreliable (due to wall reflection) and should 
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=65, J=65, K=1, ZONETYPE=Ordered
 DATAPACKING=BLOCK

the data can be read from a given section via:

      idim=65
      jdim=65
      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)
