IMAGE PROCESSING FOR SPACE TIME TRACKING OF SINGULAR POINTS METHOD FOR CHARACTERIZATION OF JET INSTABILITIES

ABSTRAKT
In this paper, we propose a tool image analysis and processing for the Kelvin-Helmholtz instability characterization. It is essentially based on a spatiotemporal tracking of singular points detected on the outline of images obtained by laser tomography. A number of characteristic parameters of the structures present along the flow are extracted allowing us to study the real jet evolution. The developed tool provides measurements of the amplification and velocity variations as well as a morphological classification of structures.
SCHLÜSSELWÖRTER: air curtain, Kelvin-Helmholtz instabilities, jet parameters, singular points, spatiotemporal evolution
