ABSTRAKT

Image processing kinematic facilities provide complementary physical analysis for flow visualization studies. Topologicat wake evolution and shed vortices understanding are complemented with full accuracy velocity field measurements followed by precise interpolation, derivative and integrate steps to determine the vorticity, pressure, and streamlines. This visualization and process analysis is applied to the study of the near wake flow around a circular cylinder for a Reynolds number of 1000.
