• G402 Improvement of the PIV using an Interpolation Technique

抄録

We attempt to improve accuracy of PIV analysis by introducing an interpolation technique for brightness distribution. This work numerically realizes decrease in uncertainty by introducing an interpolation technique. We select a Fourier interpolation technique as a interpolation technique. First, we confirm that the Fourier interpolation technique can interpolate original brightness distribution well. Then, the effectiveness of this proposed method is quantitatively investigated by using a Monte-Carlo simulation. The results show that uncertainty is decreased by applying the Fourier interpolation technique when diameter of particle image is sufficiently large.
