    Abstract

    This paper demonstrates turbulence measurements of a turbulent round jet. It is aimed to map the energy cascade and turbulent scales along the jet centerline, spanning from the developing region to the fully developed counterpart. Measurements were performed using a software-driven LDA system, which was tested and proven to deliver high accuracy measurements. The velocity static moments show a similar trend with previous jet studies, as expected. The spatial kinetic energy spectra and second-order structure functions have been compared to the Kolmogorov -5/3 and 2/3 power laws. Good agreement is only obtained in the fully developed region.
