The wakes downstream of the plates in the array are shown to exhibit behavior that varies between stable modes, flopping and quasi - stable behaviour depending on the s/t distance (where s is the spacing between the top and bottom surfaces of adjacent plates and t is the thickness of the plate). For the two and three - plate arrays with s/t = 0.25, peaks in the power spectra of about 48.2 and 98.1 Hz which correspond to Strouhal numbers of 0.06 and 0.11 are observed. For the four - plate array with s/t = 0.192, no clear peaks are visible. Probability density functions of uncalibrated hot - wire signals show that the peaks in the power do not correspond to continuously periodic fluctuations.
