Recurrence analysis of quasiperiodicity in experimental fluid data

We propose a procedure to analyze experimental data which exhibit different dynamical regimes, namely, periodicity, chaoticity and quasiperiodicity by means of Recurrence Plots (RPs). We show that, based on the recurrence properties captured by RPs, we are able to characterize successfully the type of dynamics. This approach is particularly useful for detecting the existence of quasi periodic motion in short time series. We show the capability and validity of this method by analyzing time series from fluid experiments.
