This is the readme file for averaged data of the square cylinder wake of Lyn and Rodi.
The data is stored in 21 files totaling approximately 804 KB. The first 20
files contain data from each of 20 phase angles during a period of the vortex
shedding. The 21st file (pav) contains data averaged over all the phases.
Within each of the first 20 files (with name "CMP20Pxx" where "xx" is 01 through 20
corresponding to the number of the phase angle), there are sections containing data at
fixed streamwise location and varying transverse location (measured from the center of the
cylinder). The streamwise location and the number of velocity components (one or two)
is coded in the text header for each section. The number of data points
(the number of transverse locations) and the value of the
phase angle (in degrees) are also contained in the headers.
The files (.dat) are:
CMP20p01 CMP20p02 CMP20p03 CMP20p04 CMP20p05 CMP20p06 CMP20p07
CMP20p08 CMP20p09 CMP20p10 CMP20p11 CMP20p12 CMP20p13 CMP20p14
CMP20p15 CMP20p16 CMP20p17 CMP20p18 CMP20p19 CMP20p20 CMP20pav
The name of a section (in the lines: "#@# filename =...") is coded as follows:
a_b****.suf where:
One or two component measurements are indicated by:
'a'= o : one component
'a'= t : two component
The x-position (streamwise) is determined thus:
'b' = d : downwind
'b' = u : upwind
'****' = 1000 * x/H where H is the cylinder width.
Time-information is determined by the suffix:
'suf' = avg : for averaged values
'suf' = p01 : for the 1st phase angle
...
'suf' = p20 : for the 20th phase angle
