The aim of this paper is to investigate the interrogation area size effect on the hydrodynamic results of a stirred vessel equipped with an eight flat blades turbine. Particle image velocimitry (PIV) technique was used in order to compute the velocity field in the vessel. This PIV system is equipped with a Nd:YAG 532 nm laser, a CCD camera and a mini synchronizer. In this study, it has been observed that the interrogation area size has a direct effect on the results efficiency. According to the achieved results, for a grid size between 12x12 pixel² and 128x128 pixel², it has been observed that the parameters selection has a great influence on the experimental results. Particularly, it has been noted that the maximum areas size increases by increasing the interrogation area size.
