N2 - Planar PIV was used to acquired 10, 000 independent samples of the far field of a free, turbulent round air jet flow of exit Reynolds number 20,000. The objective was to test the two-point similarity theory of Ewing et al. [1]. After applying the similarity mapping, two-point velocity correlation analysis showed independence of streamwise origin, confirming the hypothesized streamwise homogeneity in two-point similarity coordinates. The velocity data was subsequently spatially decomposed by applying Fourier transformation in the ’homogenized’ streamwise direction and POD to obtain orthogonal basis functions in the radial direction.
