Abstract

Particle Image Velocimetry is now a well-established, powerful tool for 2-D flow diagnostics. In its most common applications, a thin sheet of laser light illuminates a portion of the flow. A double exposure photograph is taken to record small light scattering particles seeding the flow. The 2-D flow field data obtained by this technique constitute great progress in comparison with single point measurements by conventional anemometry. Opposite to other whole-field techniques like smoke wire visualisation, for example, PIV is a quantitative measuring method. The opportunity to provide velocity data at one instant of time from a large field of view supports studies in the rapidly growing field of non stationary flows. This support would greatly gain, could PIV be extended in two respects:
  1. 1.

    Simultaneous recording over a certain region in depth

     
  2. 2.

    Registration of out-of-plane-components of the velocity vectors.
