Abstract
The aim of this study is to investigate the blade inclination effect in the flow generated by three different down-pitched blade turbines in a stirred tank. Particle image velocimetry (PIV) technique is used to predict the velocity fields and the turbulent characteristics. This technique consist on a 532 nm Nd:YAG laser, a CCD camera and a mini-synchronizer. In this study, it has been noted that the velocity increases with increasing the blade inclination.
