Abstract
This paper presents a statistical analysis of velocity signals for two cylinders side-by-side in a bistable flow. Time series of transversal velocity were obtained with the constant temperature hot wire anemometry technique in an aerodynamic channel. This study aims to characterize the bistable phenomena behavior by means of statistical quantities and probability density functions. Wavelet transforms are applied as a support tool for the statistical analysis. Preliminary results show a correlation between the variation of statistical moments and the bistable behavior.
