N2 - Experiments were made with 14 MEMS sensors situated along the span of a circular cylinder of aspect ratio 5. The signals of the MEMS sensors were sampled simultaneously as flow over the cylinder at Reynolds numbers of 104. The results of Wavelet analysis of the signals indicate that the percentage of time during which strong three-dimensionality of vortex shedding was detected is about 10%. As noted, strong three-dimensionality took place when the fluctuating amplitude of the. signals was severely modulated and the vortex shedding - frequency reduced was abnormally high or low. Further noted was that the addition of a splitter plate of 0.5 or one diameter in length behind the circular cylinder was not able to suppress the three-dimensionality of the flow.
