  • Analysis of turbulent mixing flow of a bluff body wake using a computer vision system
    Novak, Matej, 1968- ...
    ǂAn ǂexperimental study of the turbulent mixing flow in the wake of a prismatic bluff body was made in a non-return subsonic wind tunnel (Re[b] = 4300 to 7400) using flow visualization and a digital ... image-processing technique. A high-speed camera was used to capture smoke visualization images of the turbulent mixing flow structures. A quantitative analysis was made on time series, obtained by simultaneous digitization of the grey level in several small areas (windows) of the overall image. Fluctuations in grey level effectively corresponded to fluctuations in smoke concentration. Turbulent mixing structures in the wake exhibited various time signals and corresponding power spectra, which have been associated with space and time evolution of concentration fields. The results are compared to published velocity and concentration results.
