Abstract: Particle Imaging Velocimetry (PIV) and Laser Doppler Velocimetry
(LDV) measurements on a self-induced sloshing flow in a rectangular tank had
been conducted in the present study. The PIV measurement result was compared
with LDV measurement result quantitatively in order to evaluate the accuracy
level of the PIV measurement. The comparison results show that the PIV and LDV
measurement results agree with each other well in general for both mean
velocity and fluctuations of the velocity components. The average disagreement
level of the mean velocity between PIV and LDV measurement results was found to
be within 3% of the target velocity for the PIV system parameter selection.
Bigger disagreements between the PIV and LDV measurement results were found to
concentrate at high shear regions. The spatial resolution and temporal
resolution differences of the PIV and LDV measurements and the limited frames
of the PIV instantaneous results were suggested to be the main reasons for the
disagreement.
