A two-color particle imaging velocimetry system for supersonic flow studies Conference Paper uri icon


  • 1996, American Institute of Aeronautics and Astronautics, Inc. The objective of this study is to develop a versatile two-color Particle Imaging Velocimetry (PIV) system and demonstrate its ability to provide accurate flow velocity measurements in a supersonic flow field. The PIV system was tested with three different camera systems; a digital color CCD camera, a 35-mm camera and a 8-mm video camera. A low speed rotating wheel and a nominal Mach 2.9 flow in a wind tunnel were used as test cases for demonstrating the performance capability of the PIV system. Two-color images obtained with the particle imaging velocimetry system were analyzed using a software developed for processing two-color particle imaging velocimetry data. The data obtained shows good correlation with previously established laser doppler velocimetry data for the same tunnel configuration. The use of a 8-mm video camera was demonstrated for the first time for performing PIV experiments.
