It is clear from the principle of PIV as described that PIV — in contrast to hotwire or pressure probe techniques — is based on the direct determination of the two fundamental dimensions of the velocity: length and time. On the other hand, the technique measures indirectly, because it is the particle velocity which is determined instead of fluid velocity. Therefore, fluid mechanical properties of the particles have to be checked in order to avoid significant discrepancies between fluid and particle motion.
