Claims
- 1. A system for determining the velocity of fluid flowing around an object comprising:
- input means for generating a signal relating to an image of a fluid-flow surrounding an object, said signal being created at predetermined time intervals, said fluid-flow including particles;
- means for converting said signal into a digital signal and analyzing said digital signal to determine a centroid for each of said particles in said fluid-flow;
- means for calculating distances between said centroids of the two nearest particles in composite images generated from successive pairs of images; and
- means for generating a signal relating to a velocity distribution of said fluid-flow by dividing said distances by said predetermined time interval.
