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 |
