Abstract

In order to reveal structure of secondary flow of a turbulent bounded jet in terms of period and time delay, the wavelet cross-correlation analysis was employed to analyze cross-correlation relationships between xcomponents of the fluctuation velocities at two different points near the wall in the near field. From the distributions of the wavelet cross-correlation coefficients, similar structures of eddy motions with various scales were shown and branching of eddy structures was observed. The period of eddy can be easily determined in terms of period and time delay.
