Abstract

A hardware implementation of a Particle Image Velocimetry (PIV) system, used for 2D flow field analysis, is described. This implementation incorporates a 2048 X 2048 imaging CCD camera to replace photographic film and film scanners used in other PIV implementations. Use of this camera with an array processor and specialized software allows for the near real-time presentation of PIV data at resolution approaching film. PIV system control of both pulsed illumination and camera acquisition is accomplished via a windowed user interface running on a PC compatible computer. Novel approaches to resolving both velocity direction and zero velocity measurements are presented.
