Paper Abstract

In this paper, a DPIV system was used in which the CCD camera was so called frame straddling camera and the cross- correlation method was used for the particle image processing. For flow velocity uniformity measurements a special Pre-bias method was provided and in principle the measuring accuracy of the new method could increase to one order level. It makes the possibility to measure the uniformity of the flow velocity fields using PIV.
