ABSTRACT

The main purpose of the present study is to expand the full animation procedures applied to single CCD camera into multiple input cameras for streamwise-large image acquisition for the benefit of more realistic animation figures, especially to give more clear understanding of the aerofoil wake formation. All PIV procedures including animation jobs are completely implemented on single personal computer with single, built-in RGB image grabber. A simple pitching aerofoil model was made and it was operated within a water channel to generate multi-vision PIV images. Animation results in full colors to show the temporally continuous distribution of the instant vectors, turbulent intensity, turbulent kinetic energy, kinetic energy, vorticity and three Reynolds stress components are displayed by simple PC mouse clicks. And unsteady streaklines, trajectories and streamlines from any starting points are also represented dramatically from the multi-vision animation routines and they give deeper insig
