SEPARATION LENGTH, AZ/O 



Figure 2.11 Spanwise correlation coefficients p^g for the velocity signals measured in the wake of a vi- 

 brating cable at a Reynolds number of 1300; from Reference 22. The spanwise separation between the 

 two measuring probes is given by A Z/ D and the vibration displacement amplitude by YmaxI ^ Vibra- 

 tion frequency equal to 90 percent of the Strouhal number frequency /j.
