Abstract
The theory is developed for a particle image velocimetry measurement procedure in which particles moving in a two-dimensional region of a steady turbulent flow are photographed repeatedly to build up a statistical ensemble of flow field realizations on a single photographic plate. Each interrogation spot on the plate contains a sample of the probability density function for the two components of velocity that lie in the photographic object plane. This sample can be measured by two-dimensional spatial correlation analysis. In general, the measured probability is biased toward low velocities, but with proper experimental design this bias can be avoided.
