An experimental study of the dynamics of fluids around a vertical cylindical surface plunged into a liquid (water) was made with the aim to observe the patterns of fluid flow with the aid of the Particle Image Velocimetry (PIV) technique. For the experiment was used a system which make use of the concept of completely developed flow for reproducibility. The system was coupled to one PIV illumination system which was built with a 2 watts laser and a cylindrical polished surface bar made of steel to form an illuminated plane with which the visualization of streamlines in flow was achieved and the structure of flow present around surface of the test probe. Images and videos were recorded with a high-speed video camera in order to visualize the behavior of fluid flow of water at 25 ºC end the flow velocity was 0.025 m/s before to impact the probe made of steel AISI 304. Results show the effect of recirculation flow, growing and vortex generation in the boundary layer.
