The wavelet analysis is a time-frequency analysis method, which plays an important role in processing non-stationary signals obtained by Particle Image Velocimetry (PIV) to measure turbulent flow fields. Current research status for wavelet analysis in the flow field structure was reviewed: eduction of coherent structures and multi-scale structures(the large-, intermediate- and relatively small-scale structures)by wavelet transform and combine with the maximum energy criterion, extraction of coherent vortical structures and analysis of multi-scale turbulent structures information from the time–frequency diagram. Application of wavelet analysis in the flow structures was also prospected.
