The three-dimensional flow topology of square prism intermediate wake flow based on multi-point hot-wire measurements is investigated using wavelet analysis. A number of continuous wavelet techniques combining time and scale analysis are applied systematically to detect the primary and the secondary flow structures and to validate previously proposed topological models. Our results suggest that a preferred alternate rib spanwise arrangement similar to the one proposed by Meiburg and Lasheras [1] is plausible for the vortex topology of high Reynolds number square prism intermediate wakes. Moreover, it seems that the wake topology has a preferred spanwise wavelength of approximately 2b = 2.4d, which gives a relative spanwise/ streamwise wavelength ( 2b / λ ) of 2/5.
