ABSTRACT In this work, the effect of type of the modified attack angle of the blade on the characteristic flow patterns in a stirred vessel is studied. More particularly, three different designs of axial flow impellers were used. 3D hydrodynamic model of a mixing vessel for modified pitched blade turbines operating in laminar and turbulent regime was presented in this paper. In this model, the Navier-Stokes equations and the classical turbulence model k-? were solved using a finite volume method. To verify our computational fluid dynamics (CFD) code, the hydrodynamic flow characteristics were compared with the results published in the literature.
