Abstract: | In the present paper, the algorithm of Binary Image Cross-Correlation (BICC) was developed to measure the unsteady flow field.
A vortex flow field was used to test the algorithm by numerical simulation. The results show that BICC is an effective algorithm
for particle identification from consecutive images, the accurate velocity vector field can be obtained. The real velocity
field in a valve chamber was measured by BICC in this study. From the full-field velocity information, the pressure and vorticity
fields were also extracted by post-processing.
