The purpose of this study is to experimental investigating of the hydrodynamics structure in a cylindrical stirred vessel generated by an eight concave blades turbine. Particle image velocimetry (PIV) system was used to evaluate the effect of the blade turbine in the flow fields. The flow is illuminated by a Nd: YAG 532 nm green pulsed laser source generated in 2x30 mJ. The acquisition of the tow-dimensional images data was taken with a CCD camera with 1600 x 1200 pixels² of resolutions. In addition, a mini-synchronizer was used to control the different PIV components. For the results, we are interested to present the distribution of the velocity fields, the vorticity, the turbulent kinetic energy, the dissipation rate of the turbulent kinetic energy and the turbulent viscosity. Three azimuthally planes were carried out which present the turbine blade plane (θ=30°), the upstream turbine blade plane (θ=10°) and the downstream turbine blade plane (θ=45°).
