Abstract:

Laser particle imaging velocimetry PIV is sometimes called double pulsed laser velocimetry. PIV is a new technique to measure flow velocity and flow direction at one instant in time within a large area of the flow field. For that purpose PIV uses the light scattered by small particles in the flow, which are illuminated by two short laser pulses. This paper reports on the experience we gained with this method. In a first part our special PIV system is described. Youngs fringes method to evaluate the velocity data is discussed. Examples of our first experimental results are given.
