VISUALIZATION AND ANALYSIS OF JET OSCILLATION UNDER TRANSVERSE ACOUSTIC PERTURBATION
RÉSUMÉ
Schlieren flow visualizations of transverse oscillations of jets subjected to acoustic perturbation are analyzed in this paper. The aim is to estimate the shape and the position of the median line of the jet. Two methods are proposed for image processing; the methods are based on complementary approaches: inter-image and intra-image analysis. Synthesized images of an oscillating jet are used to validate each method and compare their performances in the case of noisy pictures. Illustrations are then shown on real laminar and turbulent jets. The results obtained using the both methods are very close, showing their reliability. Applications investigated in this paper are focused on the estimation of the convection velocity of perturbations along the jet and the influence of the Reynolds number and of the channel geometry upstream the jet formation.
