Abstract
Particle Imaging Velocimetry (PIV) and Laser Doppler Velocimetry (LDV) measurements on the 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 PIV system. The comparison parameters included the time average velocity, time average turbulence intensity, phase average velocity and phase average turbulence intensity. It was found that the PIV and LDV results agree with each other well in general for both the mean velocity and turbulence intensity, while there are some local disagreements for the turbulence intensity, which may be due to the different space resolution and the limited sample data of the PIV and LDV measurements.
