Abstract

The vorticity spectrum has been inferred, using local isotropy, from measurements of the lateral vorticity components in a turbulent wake over a small Reynolds number range. The high wavenumber part of the spectrum supports Kolmogorov's [C. R. Akad. Sci. USSR 30, 301 (1941)] similarity theory. Among the different published analytical expressions for the three-dimensional energy spectrum, the model of Kida and Murakami [Phys. Fluids 30, 2030 (1987)] is closest to the present data.
