Abstract

In this paper, the continuous and discrete wavelet transform are applied to the velocity signal of a plane turbulent jet, in order to estimate the eddy motion in the dimension of time and frequency. First, a review of the definitions of the continuous and discrete wavelet transform are described. Then, from the experimental velocity signal of a jet on the centerline, the eddy motion is analyzed in terms of instantaneous frequency and time.
