Particle Image Velocimetry (PIV) Uncertainty Quantification Using Moment of Correlation (MC) Plane

28 Apr 2018 Bhattacharya Sayantan Charonko John J. Vlachos Pavlos P.

We present a new uncertainty estimation method for Particle Image Velocimetry (PIV), that uses the correlation plane as a model for the probability density function (PDF) of displacements and calculates the second order moment of the correlation (MC). The cross-correlation between particle image patterns is the summation of all particle matches convolved with the apparent particle image diameter... (read more)
