| Abstract: | he time series of instantaneous velocity in the flows are obtained by the hot-wire technique and data sampling.Based on the data,power spectra,correlation dimension and corre-lation entropy along the lateral direction are computed,chaos indicators are analysed and the in-formation of flows along the lateral direction is given. |

| Keywords: | mixing layers correlation chaotic |
