抄録

In this study, focused on the velocity of wake after the vibrating three-dimensional square prism that changes dynamically and complexly, the systematic structures concerning the fluctuating velocity field of the wake under several vibrating conditions were evaluated by the POD analysis. The fluctuating velocity fields were numerically obtained by the Dynamic PIV system which includes double pulse YAG laser, high speed camera and so on. First mode of the velocity field under each vibrating condition looks like the distribution shape of each standard deviation. First and second modes under vortex-induced oscillation seem to play significant roles in correlation between principal coordinate of each mode and deflection of vibrating square prism.
