  • Simultaneous measurement of velocity fluctuations and smoke tracer fluctuations of turbulent flow over a back-facing step
    Novak, Matej, 1968- ...
    ǂA ǂcorrelation analysis of simultaneous measurements of velocity fluctuations measured by a Laser-Doppler-Anemometry method (LDA), and fluctuations of smoke tracer concentration measured with aid of ... computer-aided visualization method in selected segments of turbulent flow field over a back-facing step was performed. In the paper presented results indicate that the two different techniques, the Laser-Doppler-Anemometry for the velocity fluctuations and the computer-aided visualization for the concentration measurements provide accurate values when they are synchronised and analysed separately. Simultaneous association of these two techniques is allowing us to determine the velocity-concentration correlations. The presented relationship between velocity and concentration fluctuations is expressing a fairly good agreement of both measured quantities.
