Abstract

High accuracy and dynamic range have been some of the most prominent challenges when it comes to non-equilibrium turbulence measurements. LDA is one of the most preferred measurements techniques in these challenging turbulent flow measurements for its unique favorable properties in various experimental investigations. The current commercial hardware-driven LDA systems however suffer from practical limitations in accurately representing long and short residence times. A novel software-driven LDA, has therefore been developed to enhance the measurement quality and the dynamic range. A round turbulent jet has been used as the test bed that is similar to the one used for previous measurements with a typical commercial LDA. Both data are diagnosed for dynamic range in residence times and compared to each other. Much longer residence times is captured at the lowest (near zero) velocities by the novel LDA compared to that of the commercial one, which maximum value is abruptly limited at the outermost off-axis positions (52 mm).
