ABSTRACT:
A system for determining a velocity of fluid flowing around an object generates a signal for an image of a fluid-flow surrounding the object. Based on the signal, the system determines a centroid for each particle in the fluid-flow, and calculates distances between centroids of two nearest particles. The system then determines a velocity distribution of the fluid-flow based on the distances.
