Abstract

This paper demonstrates turbulence measurements across the developing region of a turbulent round jet. A high accuracy software-driven LDA system was used to obtain the radial profiles of first and second-order static moments of the streamwise velocity. Measurements were performed in radial direction at different downstream positions. The normalized profiles for the more downstream positions (15, 20 and 30 jet exit diameters) collapse, while the first position at 10 diameters deviates slightly. Similar expected trend is also seen on the first-order counterpart. These promising results indicate that the improved LDA system is uniquely suited for this kind of challenging measurements.
